Quick Answer: The Eunorau NEW-TRIKE 2.0 is a $2,499 folding trike on 20 × 3.0 tires, with a 500 W front hub motor, seven Shimano speeds, hydraulic brakes, a parking brake and a 960 Wh pack, rated for 440 lb. On the throttle over flat pavement, a 180 lb rider gets about 81 miles at 10 mph.

At 15 mph the same charge covers about 57 miles (the speed table). Eunorau lists riders from 5'1" to 6'1" and a saddle from 32.7 to 40.2 inches off the ground, and its printed figures, 32.68 inches of width among them, sit inside the e-bike definition of 40 of 51 jurisdictions, New York's included (the law section).

Who the NEW-TRIKE 2.0 is for

The Deep Crimson in Eunorau's own photograph, set on a light studio sweep we built around it for the card. The $2,499 and 500 W are listed figures, and the range section works out the 81 miles.

It is for the rider who wants a bicycle's pedals and a throttle without holding the machine up at every stop: shopping runs with a basket at each end, rides along a waterfront or through town, hills taken in a low gear, and a rider between 5'1" and 6'1" in the window Eunorau lists.

The frame steps through low, the saddle has a backrest, and the pack rides behind the seat post. Eunorau's upgrade note for the 2.0 lists what it added: "a newly added adjustable backrest, parking brake, and stylish new color", a larger pack and a "hydraulic brake system".

How we verified this Eunorau NEW-TRIKE 2.0 review

Every specification is Eunorau's, read on September 26 and again on September 30, 2026 from the NEW-TRIKE 2.0's product page, its product record and its geometry chart; each figure that takes arithmetic is recomputed, and the conflicts table shows any figure Eunorau prints two ways.

The range and fit sections close with their formulas and inputs (range, fit). The law section screens all 51 jurisdictions on the motor, the throttle, the speed, the wheel count and the width, and the Limitations date each screen and store read.

We sell the NEW-TRIKE, and the honest ledger routes each rider it suits less well to a machine of ours that suits them better. The author is Milad Ghobadibeygvand, BScN (Western University, 2014); corrections go to corrections@redtailebikes.com.

Eunorau NEW-TRIKE 2.0 specifications

Every figure in the table is Eunorau's, as its page, record and geometry chart printed it on September 26 and 30, 2026.

Eunorau's geometry chart, in the Geometry tab of the product page, prints the frame in eleven rows:

NEW-TRIKE 1.0 or 2.0: which one you are reading about

Eunorau sold a first NEW-TRIKE before this one, at the same $2,499: a listing or review that gives a 48 V 12.5 Ah pack, 30 to 40 miles or "Promax" disc levers on 160 mm rotors is describing that first trike. The 2.0 keeps the 500 W front motor, the seven speeds and the saddle range, and changes the pack, the brakes and the weight.

The 1.0 column is the Internet Archive's copy of Eunorau's first NEW-TRIKE page, captured March 20, 2025; the 2.0 column is the current page. The watt-hours are our arithmetic (volts × amp-hours).

Some reviews go further back still. Electric Bike Review's NEW-TRIKE review lists model year 2019, a 48 V 11.4 Ah pack and "Z.Star Mechanic Disc with 160mm Rotors".

The same 500 W, 80 N·m front hub, the 46-tooth chainring on a Shimano 14-28T freewheel, the 170 mm cranks, the 2.0 A charger and the 32.7 to 40.2-inch saddle range appear on both pages (archived 1.0, 2.0).

The front hub motor

The motor sits in the front wheel: Eunorau rates it at 48 V and 500 W with 80 N·m of torque, and its feature copy says it can "crank out a continuous 500 watts of power with the ability to ratchet things up to over 750 peak watts of power for hill climbs and quicker acceleration" (Eunorau's page).

The pedals drive the rear wheels through the chain and the seven-speed freewheel, so on a climb the motor pulls at the front while your legs push at the back.

A half-twist throttle moves the trike with no pedaling, and a cadence sensor brings in assist at five levels once the cranks turn. The range model holds the motor to the 500 W and 80 N·m Eunorau prints and to its 20 mph top speed (the formula).

The front wheel, cropped from Eunorau's drive-side photograph of the Deep Crimson: the hub motor at the center, with the brake rotor beside it.

On flat ground at 10 mph the model's motor turns out 5.6 N·m at the wheel; up a 12% street with 440 lb aboard, the grade asks more than the model's 80 N·m can deliver and your legs take a share (the hills section).

Seven speeds, the brakes and the controls

Seven Shimano speeds sit on the rear wheels: a 14-28T freewheel behind a 46-tooth chainring, turned by 170 mm forged alloy cranks. In the top gear one pedal turn carries the trike 5.76 meters; in the lowest, half that, which is the gear for starting up a hill (the gear section).

The drivetrain, cropped from Eunorau's photograph of the Deep Crimson: the seven-speed freewheel and derailleur at the rear wheel, the chain, and the chainring at the cranks.

The brakes are hydraulic, on 180 mm rotors, with a motor cutoff sensor and a parking brake, per Eunorau's component rows, which name the system "Hydraulic Oil Brake with Motor Cut-Off Sensor & Parking Brake". The parking brake holds the trike still while you load the baskets or climb on.

The rest, from Eunorau's page:

• The display: Eunorau's BC182 LCD, with pedal assist from level 0 to 5.
• The lights: an LED headlight and a brake taillight.
• The battery switch: "A built-in battery switch", which Eunorau credits with "easy control of power flow".
• The seat: a well-padded saddle whose backrest height adjusts, which Eunorau describes as letting you "customize it for maximum comfort and support".
• The baskets and fenders: a front basket, and at the rear "an extra large alloy basket with a solid wooden base"; the product record lists the rear rack and the fenders as included.

The frame, the fold and the width

At 32.68 inches across, the NEW-TRIKE is wider than a doorway built to the accessibility minimum: the 2010 ADA Standards set 32 inches of clear width at an accessible door, measured with the door open 90 degrees, and 36 inches where the opening runs deeper than 24 inches (§ 404.2.3). Measure the doors, gates and garage openings on your way home before you order.

Eunorau describes the fold in one sentence: "Having a folding feature on the main frame tube and telescoping stem, the trike is able to fold, and be stored away." Plan storage around the 83 cm width, which Eunorau's chart draws across the rear axle.

The Deep Crimson from behind, in Eunorau's photograph: both rear wheels on one axle, the rear basket on its wooden base, and the fenders.

At 85.9 lb, lifting it into a car or a truck bed is a job for two people. It arrives in a carton Eunorau lists at 42 × 25 × 29 inches, so plan the delivery spot around that.

NEW-TRIKE or ONE-TRIKE

Eunorau builds two trikes, and we sell both: the NEW-TRIKE 2.0 at $2,499 with a 500 W motor in the front wheel, seven speeds and a 960 Wh pack, and the ONE-TRIKE 2.0 at $1,799 with a 500 W motor at the rear, a differential and one gear. Both carry 440 lb and both fold.

Each figure from that model's page at Eunorau (NEW-TRIKE 2.0, ONE-TRIKE), read September 30, 2026, when both of our prices matched Eunorau's.

Pick the NEW-TRIKE 2.0 for gears on hills, the longer range of the bigger pack, a saddle that sets to 40.2 inches for taller riders, the parking brake, and a width that clears New York's 36-inch line and more doorways.

Pick the ONE-TRIKE for the lower price, a rear differential, and flatter rides at trike pace, with a saddle from 32.3 to 38.6 inches (our ONE-TRIKE review). Both sit in our electric trikes collection with the other three-wheelers we carry, and our Eunorau collection holds every Eunorau we sell.

How far the NEW-TRIKE goes, and what your pedaling adds

Hold 10 mph on the throttle over level pavement and a 180 lb rider gets about 81 miles from the 960 Wh pack; at 15 mph the same charge gives about 57, and with the full 440 lb aboard the 10 mph figure falls to about 49. Leave 15% in the pack, the top of the "10-15%" recharge point in Eunorau's FAQ, and the two solo rides plan at 69 and 49 miles.

Every table below comes from one saved model of this trike. Its inputs are Eunorau's front hub motor at 48 V and 500 W with 80 N·m, the 20 mph top speed, the 48V 20Ah pack and the 20 × 3.0 tires, the 85.9 lb weight from Eunorau's geometry chart, and the road physics laid out in the formula.

Your own number, in three steps:

1. Pick the speed you usually ride in the first table: 10 mph is an easy trip to the store, 15 mph a quicker commute.
2. Adjust for what rides with you and where: the weight table covers 100 lb up to the full 440, the hills table prices each grade, and the climb table gives the pace the trike holds on each one.
3. Plan from the "15% kept" column, and shift down before a climb so your legs keep adding their share.

How far does it go at my speed?

Ride slower and the charge lasts longer: 81 miles at 10 mph shrink to 40 at the 20 mph top speed, since the power it takes to push through the air climbs with the cube of your speed (Martin et al., 1998).

On the throttle alone: a 180 lb rider, level pavement, calm air at 77 °F, the one 960 Wh pack. The "15% kept" column stops charging-day math at the top of the 10 to 15% band Eunorau's FAQ gives.

Pedal along and the range runs past anything the throttle alone reaches. The model splits the work at each speed between your legs and the front motor:

The 960 Wh pack, a 180 lb rider, flat ground. An easy effort is 75 W at the cranks and a steady one 150 W.

Holding 10 mph takes 89.6 W at the wheels (Martin et al., 1998). An easy 75 W covers most of that, the pack supplies 3.0 Wh a mile for the rest, and the charge stretches to 322 miles; at a steady 150 W your legs carry the trike on their own ("legs alone").

With the motor switched off, the same equation has a 180 lb rider moving the 85.9 lb trike at about 9 mph on 75 W and about 13 mph on 150 W.

Which gear saves battery?

On the NEW-TRIKE the motor turns the front wheel and your pedals turn the rear ones, so shifting never changes what the motor spends: it sets how fast your feet turn, and your effort is what saves the pack. On the flat at 15 mph the draw is 16.8 Wh a mile on the throttle, 10.6 with easy pedaling and 4.9 with a steady 150 W.

Watt-hours a mile from the 960 Wh pack for a 180 lb rider in calm air, your pedaling measured at the cranks. A dash marks a pace the model's 500 W motor cannot hold up that grade with the effort shown.

Eunorau fits seven Shimano speeds, a 14-28T freewheel behind a 46-tooth chainring (its component rows). In the top gear one turn of the cranks carries the trike 5.76 meters, so the 20 mph top speed asks 93 pedal strokes a minute; the bottom gear asks the same 93 at 10 mph.

Trained riders measured by Marsh and Martin (1997) "maintained PC between 90 and 100 rpm at all power outputs", and less-trained riders chose lower. Shift so your feet turn at a pace you could keep up for an hour, and drop a gear or two as the road tilts up so your legs keep adding their share.

How much do hills cost, and how steep a hill can it climb?

Every 1,000 feet you climb at a steady 10 mph on the throttle takes about 164 Wh from the pack on a 4% grade and about 181 Wh on a 6% grade, over and above the same distance on the flat. Lifting a 180 lb rider and the 85.9 lb trike 1,000 feet takes about 100 Wh at the wheels, and the motor and pack turn the rest into heat.

The 960 Wh pack, a 180 lb rider holding 10 mph on each grade, calm air. At 8% the model's 500 W motor cannot keep this rider at 10 mph, so the table ends at 6%.

Steeper grades are ridden more slowly, and the next table gives the fastest steady pace the model holds on each one with the throttle alone:

Throttle only, calm air, the 85.9 lb trike plus the weight shown. With 440 lb on a 12% grade, the climb asks more torque at the wheel than the model's 80 N·m supplies at any speed, so your legs join in at a walking pace.

Does my weight change the range?

It does, and a trike carries loads: at 10 mph on the throttle, 180 lb of rider and cargo covers 81 miles, 260 lb covers 68, and the full 440 lb covers 49.

The 8% column is where weight costs most. At 10 mph up that grade the model's motor carries 130 lb of rider and cargo for 13 miles, and from 180 lb the climb needs more than Eunorau's 500 W at the wheels; ride it at the climb table's pace, or pedal along with the motor.

Rider and cargo on the 85.9 lb trike, the 960 Wh pack, calm air. "Past the model's motor" marks a climb that asks for more than Eunorau's 500 W at the wheels.

Does cold weather drain the battery?

Cold takes miles: the 81-mile ride at 10 mph comes to about 63 at 32 °F and about 57 at 14 °F. At freezing the cells hold about 89% of their 77 °F energy, the air is 9% denser, and the tires roll 18% harder (Rothhämel, 2023).

Do the tires cut range?

Less than speed or a heavy load: across the fat tires Bicycle Rolling Resistance ran on its drum, the 10 mph ride spans 72 to 102 miles, with 81 at the median. No drum figure turned up for the INNOVA 20 × 3.0, so the model uses the median of the ten fat tires the lab measured and brackets it with the slowest and the fastest; all ten are 26 × 4.00, larger than the NEW-TRIKE's.

Level pavement, a 180 lb rider on the throttle, the 960 Wh pack. The lab rolled ten 26 × 4.00 fat tires at 12 psi under 42.5 kg at 29 km/h, and each wattage converts to the rolling resistance in the first column.

Eunorau's 60 to 100 miles, as rides

Eunorau prints "60-100 Miles" for the 960 Wh pack. In the model, 60 miles is a 180 lb rider holding 14.4 mph on the throttle over level ground, 16.0 Wh a mile; 100 miles is 5.8 mph on the throttle, or 14.4 mph with an easy 75 W of pedaling, 9.6 Wh a mile. Eunorau's page prints the band in its highlights and its range row.

The top of Eunorau's band is a pedaling figure: a relaxed pace with your legs turning covers it. Carry a full load, ride in winter or climb, and the weight, cold and hills tables show what each one takes.

Plan on 85% of your row and keep the rest in the pack: 81 miles at 10 mph become 69, and 57 at 15 mph become 49.

How the range tables are computed

Each row begins with the power the wheels need to hold one steady speed, from the road-power equation Martin and colleagues checked against road measurements in 1998:

Wheel power = v × [ m × g × (Crr × cos θ + sin θ) + ½ × ρ × CdA × v² ]

v is the speed, m the rider, cargo and trike together, g gravity, θ the angle of the grade, Crr the rolling resistance (0.0105 is a drag of 1.05% of the weight on the tires, the median fat tire on the lab's drum), ρ the air's density and CdA the drag area of rider and trike. On three wheels the rolling term applies to the whole weight, whichever wheel carries it.

Four steps take that wheel power back to the cells:

1. Your pedaling reaches the rear wheels through the chain at 97.7% (Martin et al., 1998), and the front motor supplies whatever is left.
2. The motor borrows its curve from a motor with published figures, Bafang's RM G0H0: 510 rpm unloaded, 426 rpm at its rated point, efficiency "≥ 80" percent. The model scales that curve to the NEW-TRIKE's 48 V and 500 W, fits the unloaded speed at 22.8 mph so a 180 lb rider on the throttle tops out at Eunorau's 20 mph, and limits the torque to Eunorau's 80 N·m.
3. The pack spends part of its energy inside itself; on the 48 V pack Arango, Lopez and Ceren measured, that is 3.0% at 10 mph on the throttle.
4. Watt-hours a mile are the cells' watts over the speed, and miles are the 960 Wh, reduced for what cold leaves in the cells, over the watt-hours a mile.

A worked example: a 180 lb rider holding 10 mph on the throttle over level pavement. Rolling takes 55.7 W and the air 33.8 W, 89.6 W at the wheels in all.

At 10 mph the 21.98-inch front wheel turns 152.9 times a minute. The motor model (1.316 N·m per amp, a 0.607 Ω winding and 0.55 A drawn unloaded, each worked out from Bafang's published figures at 48 V) delivers 5.6 N·m on 4.8 A, 78% efficient at this light load.

The motor draws 115.2 W and the cells, adding the pack's own losses, supply 118.7 W: 11.9 Wh a mile at 10 mph. Before rounding it is 11.87, and 960 ÷ 11.87 gives 80.9 miles, or 68.8 with 15% kept.

The model checked against the figures it was built from:

Martin and colleagues' own case (Appendix I: 90 kg on a 0.3% grade at 8.36 m/s) and the RM G0H0's rated point from Bafang's workbook.

What the 440 lb payload covers

Eunorau rates the NEW-TRIKE for a 440 lb total payload, and in its own guide Eunorau defines payload this way: "Payload covers the rider and anything carried on the bike itself." So the 440 lb is you plus what rides in the baskets, and the trike's own 85.9 lb is never taken out of it.

Say a 220 lb rider carries 40 lb of shopping across both baskets: 260 lb, leaving 180 lb of the rating unused. At 10 mph on the throttle that trip runs about 68 miles on one charge, against 81 for a 180 lb rider riding alone (the weight table).

The baskets are for cargo, and a child rides only in a seat made for one.

How a child may ride is set by each state; California's statute is one example: a passenger rides "upon or astride a separate seat attached thereto", and one "four years of age or younger, or weighs 40 pounds or less" needs a seat that holds them in and shields them from the moving parts (Cal. Veh. Code § 21204(b)). Count any seat and the child inside the 440 lb.

Riding three wheels: corners, slopes and stops

Three wheels stand up without you, and that changes how the trike corners. Eunorau's FAQ for its other trike, the ONE-TRIKE, puts it plainly: three wheels "provide a stable platform when starting, stopping, and riding at lower speeds. However, a trike handles differently from a bicycle and does not lean naturally into turns."

The same FAQ gives the advice for a new rider: "practice in a flat, open area and slow down before cornering", and take "extra caution on steep hills, loose surfaces, and side slopes".

For the first rides, then: an empty parking lot, slow circles in both directions, stops from 10 mph with both levers, and every corner taken at a walking pace until it feels ordinary. Keep heavy shopping low in the baskets, set the parking brake before you step off, and on a sideways slope keep your speed down.

Will the NEW-TRIKE fit you?

Eunorau sizes the NEW-TRIKE for riders from 5'1" to 6'1", and at 109% of inseam the formula sets the saddle top 25.1 inches from the crank axle for the median 5'1" rider in the US Army's ANSUR II survey and 32.1 inches for the median 6'1" rider.

That is a distance you can measure at home, along the seat post from the center of the crank axle to the top of the saddle.

The tables run the survey's 6,068 measured bodies through the formula at every height from 5'0" to the top of Eunorau's window.

Eunorau's saddle row sets the seat from 32.7 to 40.2 inches off the ground, and its geometry chart puts the crank axle 10.6 inches up (row E, 270 mm). The second table below works out who those two figures settle.

Find your fit in three steps:

1. Measure your inseam in socks. Stand against a wall, pull a hardback book up firmly between your legs where a saddle would sit, and measure from the floor to the top of the book.
2. Find your height in the first table and check that your inseam sits inside its row; a longer inseam reads like the row above.
3. Set the saddle to your row's distance when the trike arrives, then fine-tune with the knee and heel checks near the end of this section.

How high should the saddle go?

For the median rider at each height the formula distance runs from 25.1 inches at 5'1" to 32.1 inches at 6'1". The formula puts the saddle 109% of your inseam above the pedal axle (Peveler et al., 2005), and published practice runs from 106% to 110.4% (Ferrer-Roca et al., 2012); the last two columns give both ends.

Taking Eunorau's 170 mm crank off the pedal-axle figure gives the distance from the crank axle, the point you can measure from at home.

The formula's distance from the center of the crank axle to the top of the saddle, along the seat post, for the median rider at each height at 109% of inseam, and at 106% and 110.4%. ANSUR II bodies, women and men together; the inseam column runs from the 5th to the 95th percentile at that height.

Eunorau's own figures settle two things for certain. Take the 10.6-inch crank axle height off the listed saddle heights, and the saddle top sits 22.1 inches above the crank axle at its lowest and 29.6 inches at its highest.

A saddle is never closer to the crank axle than the height between them, so a rider whose formula distance is under 22.1 inches finds even the lowest setting too high, and one whose distance is 29.6 inches or less is reached by the top setting:

Riders of 100 at each height whose formula distance, at 109% of inseam, falls under 22.1 inches (the lowest setting is too high for them) or at 29.6 inches or less (the top setting reaches them), from Eunorau's listed 32.7 and 40.2 inches and its 270 mm bracket height. The rest of each row turns on the seat post's angle.

From 5'1" to 5'4" the top setting reaches every rider modeled, and at 5'6" it reaches 94 of 100; from 5'1" up, no rider's formula distance falls under the 22.1 inches that would put even the lowest setting too high.

Above 5'6", how far the top setting reaches depends on how far the seat post leans back, since a leaning post carries the saddle away from the crank as it rises; set the saddle to your row's distance on delivery and measure it before you ride.

Can I put a foot down at a stop?

You don't need to: three wheels hold the NEW-TRIKE up at a stop, so you stay seated with your feet on the pedals or the ground. Getting on, the frame drops low between the seat post and the head tube, and you step through it instead of swinging a leg over.

The height of that low point is not printed on Eunorau's geometry chart, so no clearance is computed here (Limitations).

Will I feel cramped, or stretched out?

Eunorau's chart puts the top of the head tube 18.8 inches above the crank axle and 17.4 inches ahead of it (477 mm of stack, 441 mm of reach), and the stem is the part you adjust. Eunorau describes it as "foldable, adjustable" with a quick-release clamp that "allows for easy height and angle adjustments".

How far you lean also depends on the stem's setting and the bars, and no stem or handlebar dimension is published for the NEW-TRIKE (Eunorau's component rows), so no lean angle is computed. Raise the bars and bring them back toward you, and you sit more upright.

How much weight goes on my hands?

The more upright you sit, the less your hands carry, since less of your trunk leans out ahead of the saddle; no grip position is published for the NEW-TRIKE, so no hand-load figure is computed. For scale, ten road racers pedaling on the hoods put 15% of their weight on the stem (Carahalios, 2015).

If your palms or wrists ache on a longer ride, raise the stem and tilt the bars back: an upright trunk puts more of its weight on the saddle (Clauser et al., 1969 give each body segment's share of body weight). The backrest helps too, holding your back where it rests. Padded gloves cut the pressure over the ulnar nerve by 10 to 28% in 36 experienced cyclists (Slane et al., 2011).

How do I set the saddle when it arrives?

Start at your row's distance, then look at your knee: with the pedal at the bottom of its stroke it should stay bent 25 to 35 degrees (Peveler et al., 2007). The heel check is the quickest way there: rest your heel on the lower pedal and raise the saddle until that leg is just straight. Among 19 trained cyclists, that method put 70% inside the knee range, more than either inseam formula did (Peveler et al., 2005).

Open the quick-release seat clamp, set the height with the heel check, close it firmly, then set the backrest to meet your lower back.

How we computed fit

One rule builds the first table: the saddle goes 109% of your inseam above the pedal axle, and the 170 mm crank comes off to give the distance from the crank axle.

Take a 5'8" rider with the survey's median inseam for that height, 32.6 inches. The saddle belongs 35.6 inches above the pedal axle, and 28.9 inches above the crank axle once the crank comes off; the LeMond method, 88.3% of inseam, gives 28.8. That 28.9 is under the 29.6 the top setting reaches, so this rider is covered.

The formula holds on the survey itself: across all its bodies, the LeMond method plus a 170 mm crank comes to 109.0% of inseam from the pedal, against 109.2 ± 0.9% measured in trained cyclists (Peveler et al., 2005).

Eunorau's geometry drawing could not be scaled to its own table within 3.5%, and its photographs are three-quarter views, so nothing is measured from them; no seat angle, standover, lean or hand load is computed (Limitations).

The Mercer fit test

We hold every machine we review up against one family, the Mercers; each verdict reads a figure Eunorau prints, or the fit tables' row at that person's height.

The inputs: Eunorau's 5'1"–6'1" window, the listed saddle heights of 32.7 to 40.2 inches, the saddle distance and the bound in the saddle tables, the 440 lb payload, the 85.9 lb weight, the 32.68 inch width, and the law in the next section.

For Ruth, Maya and Dana, Eunorau's own figures confirm the top setting for most riders their height; Frank, Cole and Jack sit inside Eunorau's window and set the saddle on delivery by the heel check in the setup section. Ivy's turn comes on a machine made for her size.

What the law calls it: 500 W, a throttle and three wheels

On September 30, 2026 we set the NEW-TRIKE's printed figures, a 500 W motor, a throttle, 20 mph, three wheels and 32.68 inches of width, against the electric-bicycle definition of every state and the District of Columbia, and they sit inside 40 of them.

Federal law counts three wheels in: under 15 U.S.C. § 2085(b) a low-speed electric bicycle is "a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.)".

New York is among the 40. Its code defines an electric bicycle as "a bicycle which is no more than thirty-six inches wide" (VTL § 102-c), and a bicycle as "every two or three wheeled device" ridden by human power through a chain, "with such wheels in a tandem or tricycle" (§ 102); at 32.68 inches the NEW-TRIKE sits under the width line.

Five states write an e-bike on two wheels, directly or through their definition of a bicycle, New Jersey among them, whose definition also allows assistance only while the rider pedals; four leave the wheel count unsettled. Alaska and Kentucky define no electric bicycle at all. On October 1, 2026 Connecticut's amended wattage takes effect, and since its wheel count stays open, the count of 40 does not move.

The five jurisdictions whose definitions leave the NEW-TRIKE's printed figures out, and the four where the statute's text leaves the wheel count open, each in its own words, from our three-limb screen of all 51 on September 30, 2026: the motor, speed and throttle limbs from our rule table, then the wheel count and the width.

Outside a state's definition, the state's code governs the trike as whatever other vehicle it names, and the statute in each row says where to read which. Our state guide links each state's own page, including New York's and New Jersey's.

In the three-class states, a throttle that carries the trike to 20 mph and stops there makes it Class 2. California writes that class as a motor "that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour" (Cal. Veh. Code § 312.5(a)(2)), and counts a bicycle as a device "having one or more wheels" (§ 231).

What Eunorau's "Class 2" label means here

The NEW-TRIKE's highlights read "Class 2 Speed limited Unlockable", and its speed row prints "20MPH / 32KMH under speed limited/locked" beside a half-twist throttle. This review screens the trike on those printed figures, which California's class wording quoted above reads as Class 2. Ridden past 20 mph with assist, it leaves that wording, and your state's rules for faster machines govern it.

Charging and battery care

The NEW-TRIKE comes with a 2.0 A charger, and at 2 A the 960 Wh pack fills from empty in about 8.8 hours; Eunorau's spec row prints "4 - 6 hours", and its FAQ puts a full charge on its bikes at "between 3-8 hours" depending on the battery and charger.

Eunorau's 48 V charger listing prints "Output Voltage: 54.6V", so 2 A delivers 109.2 W; the charger's slowdown near full is left out.

Few rides empty the pack. A 20-mile ride at 10 mph on the throttle takes about 240 Wh from the cells (the speed table), which the 2.0 A charger puts back in about 2.2 hours.

The 48V 20Ah pack behind the seat post, cropped from Eunorau's photograph of the Deep Crimson, with the backrest and saddle above it.

Eunorau places the pack "behind the seatpost" and fits it with a switch of its own (the product page). Its general FAQ asks you to recharge while 10 to 15% remains and to store a pack left longer than two weeks "in a cool, dry place with a 70%-80% charge remaining"; it says Eunorau batteries "typically last 5-6 years" and "still deliver more than 80% of their original capacity after 500 charge cycles".

Where Eunorau prints a figure two ways

Eunorau describes the NEW-TRIKE 2.0 on its product page, in its product record and in the geometry chart on the page, and described the first generation on a page the Internet Archive kept. Where two of those differ, the last column gives the figure this review uses.

Eunorau's page and record as read on September 26 and again on September 30, 2026, with no change between the two reads; the archived first-generation page as captured on March 20, 2025, and the warranty policy on September 26.

Has it been recalled?

Neither Eunorau nor the NEW-TRIKE appears in a federal recall. On September 30, 2026 both names went through three fields of the CPSC's recall database, the title, the description and the product name, each shown answering by a control query, and each of the 51 recalls whose titles name an electric bicycle, an e-bike or an electric scooter was read for either name.

The CPSC's warning listing held 373 rows on September 30, 2026: two name a control brand, and none names Eunorau or the NEW-TRIKE.

Is it UL certified?

Eunorau's NEW-TRIKE page marks the model "UL CERTIFIED: Yes" in its highlights. Two standards cover an e-bike's electrics: UL 2849, for the whole electrical system, and UL 2271, for the battery. If a building manager, a senior community or an insurer asks for the certificate, add a note to your order and we will request it from Eunorau.

Warranty, and who handles a claim

Coverage by part under Eunorau's warranty policy, read on September 26, 2026:

The policy is issued by Eunorau Bikes, "a Nevada corporation", for US purchases made from August 1, 2023, and covers manufacturing defects in the parts Eunorau fitted (the policy).

It carries three conditions (the policy): cover for "the original purchaser", "Product Registration right after the purchase", and an "E-bike check-up by a Eunorau specialist or dealer after the first year of use"; wear parts and labor sit outside it. Our Eunorau brand profile lays these terms beside the rest of the range.

Buy the NEW-TRIKE from us and we run any warranty claim. Send a photo and a line about what failed; we take it to Eunorau and follow it until the part reaches you.

The honest ledger

Green flags

• A 960 Wh pack: about 81 miles at 10 mph on the throttle for a 180 lb rider, and Eunorau's 100 miles at 14.4 mph with easy pedaling (the range tables).
• Seven Shimano speeds behind a front hub motor with 80 N·m, so your legs share the climbs at a cadence you choose (the gear section).
• Hydraulic brakes on 180 mm rotors with a parking brake, and a motor cutoff sensor on the levers (the parts section).
• 440 lb of rider and cargo, the trike's own 85.9 lb counted apart, with a basket at each end (the payload section).
• 32.68 inches wide, under New York's 36-inch line, with a frame and stem that fold and a backrest saddle (the frame section).
• $2,499, Eunorau's own price on September 30, 2026, in three colors (buying from us).

Red flags: where it is the wrong trike, and what to do

• A budget under $2,000: the ONE-TRIKE 2.0 is $1,799, with a rear differential and one gear; read our ONE-TRIKE review.
• Taller than about 5'9": the top setting's reach turns on the seat post's angle, so read the saddle tables, measure on delivery, or send us your inseam first.
• A doorway, gate or path narrower than 32.68 inches: measure first; Eunorau's chart draws that width across the rear axle (the frame section).
• Riding in a state that defines an e-bike on two wheels: read the law section and your state's own page before you ride on its roads.
• Steep hills with a heavy load: up 12% with 440 lb aboard, the model needs your legs as well; use the low gears (the hills section).
• Two riders: the NEW-TRIKE has one seat; for a child, fit a seat made for one and read your state's passenger rule (the payload section).

Who should buy it

Buy the NEW-TRIKE 2.0 if you want three wheels for stops and errands, gears for the hills where you live, a pack that covers a long day, hydraulic brakes with a parking brake, doors wider than 32.68 inches, and a state whose definition takes in a three-wheeler, for $2,499.

Take the ONE-TRIKE 2.0 instead if your rides are short and flat and the $700 difference matters more than the gears and the pack.

Skip both if the trike has to go up stairs or through a narrow gate: at 85.9 lb and 32.68 inches across, it lives at ground level.

Before you buy: the checklist

Nine checks: the first five decide whether the NEW-TRIKE is your trike, and the last four get the order and the first week right.

• ☐ Measure every doorway, gate and garage opening on your route home, door open, against 32.68 inches.
• ☐ Look up your state's e-bike definition for the wheel count; our state guide is the place to start.
• ☐ Measure your inseam in socks and find your row in the saddle tables; from 5'9", plan to set the saddle on delivery.
• ☐ Add up rider, cargo and accessories against the 440 lb; the 85.9 lb trike sits outside it.
• ☐ Carrying a child? Budget for a seat made for one, and read your state's passenger rule.
• ☐ Plan your longest ride at 10 mph on the throttle: one charge plans 69 miles for a 180 lb rider on the flat.
• ☐ A full charge from empty at 2 A takes about 8.8 hours, so plan the first evening around it.
• ☐ Ride slow circles and stops in an empty lot before the street, and set the parking brake whenever you step off.
• ☐ Look the carton over before the driver leaves, and if anything is damaged, send us photos within 48 hours.

Limitations of this review

Twenty limits on this review, each numbered and tied to the section it qualifies.

1. The NEW-TRIKE 2.0's specifications are Eunorau's figures from its page, record and geometry chart, recomputed wherever arithmetic enters. The exceptions are our range and fit models, the jurisdiction screen and our store terms, set out below.
2. Every range row is one steady speed on one grade in still air. Stops, starts and headwinds cost more, and a trike on errands stops often; a tailwind costs less.
3. Eunorau prints the charging time, the first generation's pack, the motor's power, the wheelbase, the chain stay, the range and the warranty more than one way (the conflicts table); the review works from the figure named there.
4. The charging hours are arithmetic from the 2.0 A charger and the 54.6 V Eunorau prints for its 48 V charger, and leave out the charger's slowdown near full.
5. The jurisdiction screen sets the printed 500 W, throttle, 20 mph, three wheels and 32.68-inch width beside each definition as our rule table, our wheel-count reading and the statutes stood on September 30, 2026. It reads the definitions only, leaves passenger and age rules to each state, and is not legal advice.
6. Four jurisdictions are left unsettled on the wheel count. Connecticut's § 14-1 and Vermont's § 4 define no "bicycle"; Missouri's wheel-counting definition is written for §§ 307.180 to 307.193 only; and whether Arkansas's code counts a three-wheeler as a bicycle could not be read, because the official code is published through LexisNexis public access, which did not answer on September 29 or 30, 2026.
7. The recall screens ran on September 30, 2026 on three fields of the CPSC database, each shown working by a control query, and on the 51 recalls whose titles name an electric bicycle, an e-bike or an electric scooter. That second set is a floor and not the whole database, since a recall titled by a brand name alone escapes a title search; the warning listing's 373 rows were read the same day, and neither source names Eunorau or the NEW-TRIKE.
8. Our price, orderability and Shop Pay terms come from our own listing; the payments are its plan table for $2,499 at 15% APR, read September 30, 2026.
9. The motor model is a comparable, not a measurement of this motor. Eunorau prints the NEW-TRIKE's 48 V, 500 W and 80 N·m in a front hub; the curve is Bafang's RM G0H0 geared hub, set at the driven wheel, with the unloaded speed fitted so a 180 lb rider reaches Eunorau's 20 mph and no faster. The "over 750 peak watts" in the feature copy is not modeled.
10. No drum or road measurement of the INNOVA 20 × 3.0 tire was found. The tables use the median of ten 26 × 4.00 fat tires on Bicycle Rolling Resistance's drum, bracketed by the slowest and the fastest of the ten.
11. The drag area is the upright cruiser figure of 37 everyday riders; no field measurement of a trike's drag area was found, and the baskets and the wider rear add frontal area the model does not count.
12. The cold rows use McMaster's measured LG HG2 cell as the central line, bracketed by Samsung's 35E data sheet and Casado et al., 2025; Eunorau names Samsung cells without naming the cell model.
13. No ride of the NEW-TRIKE 2.0 to empty, with its speed and load stated, was found in print, so the chain from wheel to pack is checked link by link against its sources, with no whole-ride figure to test it against.
14. The weight in the model is row J of the geometry chart, 85.9 lb; the spec rows print no weight of their own.
15. The fit tables use the bodies of US Army personnel. ANSUR II measured 6,068 soldiers aged 17 to 58 in 2010 to 2012; how inseam varies at a given height should carry over to civilians, while the exact spread may not.
16. The fit is the formula alone. Eunorau's geometry drawing, scaled by its own total-length line or by its front tire's size, reproduces at most two other rows of its chart within 3.5%, and its gallery holds three-quarter views, so no seat angle, standover, grip position, lean or hand load is measured; Eunorau's chart and pages print none of them. The saddle bound reads Eunorau's listed saddle heights over its 270 mm bracket height.
17. Eunorau prints no folded size for the NEW-TRIKE 2.0, so the frame section gives the shipping carton and the unfolded width.
18. Treat the saddle formula as a first setting. Among 19 trained cyclists, the inseam formulas put 55 to 65% inside the 25 to 35 degree knee range and the heel check 70% (Peveler et al., 2005); finish the setting on the trike.
19. The handling advice quotes Eunorau's FAQ for the ONE-TRIKE, its other trike, since the NEW-TRIKE 2.0 page carries no FAQ; the payload section quotes California's statute as one example and does not screen every state's passenger, helmet or age rule.
20. The ADA figures describe accessible doors, not every door. Many doors are wider or narrower than those minimums, which is why the page asks you to measure. Until September 30, 2026 this page worked from Eunorau's rows alone; the range, fit and law sections now compute each ride, each rider and each state. Expiry: re-verify if Eunorau changes the motor, pack, speed setting, payload, rider window, saddle heights, geometry or width, if our price moves, or if any state's definition changes.

The source register

What this review rests on, by tier and by what each source supports: Eunorau's pages, record, chart, photographs, guide and FAQs, the archived first-generation page, the statutes and federal standards, the CPSC's lists, the published measurements under both models, and our own datasets.

Frequently asked questions

Is the Eunorau NEW-TRIKE 2.0 a good electric trike?

For a rider who wants three wheels, gears for hills and a long range, it is a well-equipped $2,499 trike: seven speeds, hydraulic brakes with a parking brake, 440 lb of payload and a frame that folds. You get about 81 miles on a charge at 10 mph on the throttle at 180 lb, and if your rides are short and flat, the $1,799 ONE-TRIKE is the other trike to read (the family section).

What is the difference between the NEW-TRIKE 1.0 and 2.0?

The pack, the brakes and the weight: the 2.0 carries 48 V 20 Ah (960 Wh) in place of the 1.0's 12.5 Ah, hydraulic brakes on 180 mm rotors with a parking brake in place of Promax levers on 160 mm, and weighs 85.9 lb against 88.1. Your motor, gears and saddle range are the same on both (the generations table).

Do electric trikes have gears?

Yours has seven: a Shimano 14-28T freewheel behind a 46-tooth chainring. In the top gear one pedal turn moves you 5.76 meters, so the 20 mph top speed asks 93 pedal strokes a minute; shift down for hills so your legs keep helping (the gear section).

Can an electric trike go up hills?

Yes, at a pace set by the grade: in the model your NEW-TRIKE holds 14.6 mph up a 4% street with 180 lb aboard, 9.8 mph up 8% and 7.1 mph up 12% on the throttle alone. With the full 440 lb a 12% grade takes your legs as well, which is what the low gears are for (the hills section).

How far does the NEW-TRIKE 2.0 go on a charge?

About 81 miles at 10 mph on the throttle from the 960 Wh pack if you weigh 180 lb and ride flat pavement, and about 57 at 15 mph. With the full 440 lb aboard your 10 mph ride comes to about 49, and keeping 15% in reserve your 10 mph plan is 69 (the range tables).

How long does the NEW-TRIKE 2.0 take to charge?

About 8.8 hours from empty on the 2.0 A charger it ships with, by our arithmetic, where Eunorau's spec row prints 4 to 6 hours. A 20-mile ride at 10 mph goes back in about 2.2 hours, so you rarely charge from empty (the charging section).

How wide is the Eunorau NEW-TRIKE 2.0?

83 cm, which Eunorau's geometry chart gives as 32.68 inches, measured across the rear axle. A door built to the ADA's 32-inch minimum is narrower than your trike, so measure yours with the door open (the frame section).

Does the NEW-TRIKE 2.0 fold?

Yes: Eunorau describes "a folding feature on the main frame tube and telescoping stem", so the trike "is able to fold, and be stored away". Plan your storage around the 83 cm width across the rear axle and the 85.9 lb weight (the frame section).

Do electric trikes tip over?

Eunorau's FAQ for its ONE-TRIKE names the two places to take care: a trike "does not lean naturally into turns", so slow before corners, and it asks for "extra caution on steep hills, loose surfaces, and side slopes". Load heavy items low, and practice in an open lot first (the handling section).

Are electric trikes safe for seniors?

Three wheels take away the balancing at a stop, which Eunorau's ONE-TRIKE FAQ describes as "a stable platform when starting, stopping, and riding at lower speeds", and the NEW-TRIKE adds a backrest, hydraulic brakes and a parking brake. Your saddle row and the width of your doors are the fit checks to make first (the fit section).

How fast does an electric trike go?

Your NEW-TRIKE's top speed is the 20 mph Eunorau prints, reached on the throttle; in the model a 180 lb rider on the flat settles right at 20. Pedaling helps at any speed, since the top gear asks 93 pedal strokes a minute at 20 mph (the gear section).

How much weight can the Eunorau NEW-TRIKE carry?

440 lb of you and your cargo, by Eunorau's definition of payload as "the rider and anything carried on the bike itself", with the trike's own 85.9 lb outside that figure. At the full 440 lb your 10 mph throttle ride on one charge covers about 49 flat miles (the weight table).

What height is the Eunorau NEW-TRIKE 2.0 for?

Eunorau lists riders from 5'1" to 6'1", with the saddle 32.7 to 40.2 inches off the ground. A 5'8" rider with the survey's median 32.6-inch inseam sets the saddle 28.9 inches from the crank axle, within the 29.6 inches Eunorau's figures confirm the top setting reaches; from 5'9" up, set your saddle on delivery by the saddle tables.

Are electric trikes street legal?

Where the state's e-bike definition takes in three wheels. On September 30, 2026 your NEW-TRIKE's printed figures sit inside 40 of 51 jurisdictions, New York included at 32.68 inches wide, and five states write their definitions on two wheels (the law section).

Do you need a license for an electric trike?

That turns on your state's definition. Where it takes in the NEW-TRIKE's 500 W, throttle, 20 mph and three wheels, your state's e-bike rules apply; where it does not, the state's code governs the trike as another vehicle, and the statute in the class table shows which.

Is an electric trike better than an electric bike?

It trades a narrower, lighter machine for one that stands on its own: three wheels hold you up at a stop, and your NEW-TRIKE is 32.68 inches wide and 85.9 lb. If you want two wheels and cargo, our MAX-CARGO review covers Eunorau's long-tail.

How much does an electric trike cost?

The NEW-TRIKE 2.0 is $2,499 in any of three colors, the same as Eunorau's own price on September 30, 2026; the ONE-TRIKE 2.0 is $1,799. Shop Pay splits your $2,499 into 3 payments of $853.91, 6 of $434.91 or 12 of $225.56 at 15% APR (the buying section).

Is Eunorau a good brand?

Eunorau names its parts and publishes its terms: on the NEW-TRIKE 2.0, Samsung cells, Shimano gears, hydraulic brakes, a 10-year frame warranty and a "UL CERTIFIED: Yes" mark. Our Eunorau brand profile covers the full range.

Where are Eunorau bikes made?

Eunorau's FAQ says its bikes are "designed in the U.S. and manufactured in Shanghai", and that a team there oversees quality control and inspects every bike before it ships.

The bottom line

The Eunorau NEW-TRIKE 2.0 is a 500 W front-motor trike with seven speeds and a 960 Wh pack, rated to 440 lb: a $2,499 folding three-wheeler on 20 × 3.0 tires with hydraulic brakes, a parking brake, a backrest saddle and a basket at each end, inside the e-bike definitions of 40 of 51 jurisdictions.

A 180 lb rider gets about 81 miles at 10 mph on the throttle, 57 at 15, and 49 at 10 mph with the full 440 lb aboard.

Buy it for stops with your feet up, errands with room to carry, and hills taken in a low gear, from 5'1" to 6'1", with doors wider than 32.68 inches. If your rides are short and flat, read our ONE-TRIKE review first.
