Freesky Extra Battery Pack
This is the genuine Freesky Extra Battery Pack, $480–$799, in 17 versions. Freesky sells it in 17 fitments, 14 of which match a bike we list. 17 of 17 can ship today — we match Freesky's own live availability rather than take orders for something nobody has.
What it fits
Freesky publishes fitment in the option name rather than in a compatibility chart, so we have read it out and checked each one against the Freesky bikes Redtail actually lists. An option marked not listed here fits a Freesky model we do not carry — it will still be the right part if you own that bike.

Shipping, returns & support
Shipping
Parts and accessories may ship separately and can take longer. Redtail's free-shipping promise is written for electric bikes — it is not a promise on a part, and no parts page here claims one. Orders are prepared and dispatched within 1–3 business days of confirmation.
On delivery
Inspect your shipment at delivery. Damage, defects, or incorrect items must be reported with photos within 48 hours; claims submitted after this window are not accepted.
Returns
Change-of-mind returns accepted only on unopened, factory-sealed items requested within 72 hours (3 days) of delivery, with a 15% restocking fee plus return shipping. Once a box is opened or a bike is ridden, it is no longer eligible.

Frequently asked questions
Is this a genuine Freesky Extra Battery Pack?
Yes. It is Freesky's own part, listed from Freesky's published catalogue and price-matched to their US store. We are not substituting a generic equivalent.
Will the Extra Battery Pack fit my bike?
Check the fitment table above — we have read Freesky's option names and marked which ones match a bike we list. If your model is not covered there, send it to us and we will confirm with Freesky in writing before you order.
Does this ship free?
Redtail's free-shipping promise is written for electric bikes. Parts and accessories may ship separately and are quoted at checkout.
How do I claim if it arrives damaged?
Inspect your shipment at delivery. Damage, defects, or incorrect items must be reported with photos within 48 hours; claims submitted after this window are not accepted. Send us photos with your order number and we handle it — you do not deal with the manufacturer.
Is the price here the same as buying direct?
Yes. We match Freesky's own US price in USD and re-check it every day, so this page follows what they actually charge.
