36v Rack Batteries (10.5ah and 17.5ah)


Designed for use with any 250w motor & controller set-ups, the 36v REV Rack batteries can be used as a primary or secondary battery for any 250w kit or bike, or a replacement / secondary battery on many 36v 250w e-bikes.

The battery is lockable for security, and simple to unlock and remove from the bike for easy charging. The package includes the compatible rack, which can mount a bag or basket on top.   Note; the 16.5ah battery does not have a controller box at the front, as the other sizes do.

This battery has an on/off switch, and a bonus rear light is attached.



Ideal for step-through bikes
36v pack with rack included, and 3A charger

Rack batteries are designed to mount over the rear wheel, and are adjustable in height to suit bikes with 24-29″ wheels. They can be mounted over smaller wheels too, but will sit a bit high.

Rack batteries are necessary with cruiser-style (curvy) frames, or frames with a small or no diamond (such as step-through frames). This position leaves the bulk weight quite high over the back of the bike, which is not ideal for the best balance of the bike. This can be ok for general commuting or leisure riding, but we generally recommend frame-mounting batteries wherever possible, especially for sporty applications.

Rack batteries cannot be used on Dual Suspension MTBs, without some significant modification to the forward mounting points.  This is not recommended.
