Rack Battery

Rack-mount eBike batteries combine dual functionality — serving as both the energy source for your motor and a structural rear rack — giving your e-bike a clean, integrated look without a separate rack accessory.

What is a rack-mount battery?

A rack battery mounts on the bike's rear rack position and integrates the battery into a carrier that also functions as a rack top surface. This integrated design looks cleaner than frame-mounted batteries and keeps the centre of gravity low and rearward — beneficial for loaded commuting bikes.

Can I mount panniers on a rack battery?

Yes — most rack batteries feature standard attachment points for aftermarket panniers and bags. Verify pannier compatibility with your specific rack battery model before purchasing. Browse our pannier collection for compatible bags.

What voltage and capacity options are available for rack batteries?

EBikeBC's rack batteries are available in 36V and 48V configurations with capacities from 10Ah to 17.5Ah. The choice depends on your motor's voltage requirement and desired range per charge.

Are rack batteries easy to remove for charging?

Yes — rack batteries typically use a key-lock slide-off mechanism for easy removal. This allows you to bring just the battery indoors for charging rather than carrying the whole bike, which is particularly convenient for apartment dwellers in Canadian cities.

Is a rack battery compatible with all e-bike frames?

Rack batteries require standard rear rack mounting eyelets on the seat stays and seat tube. Most aluminium commuter and hybrid frames include these mounts. Carbon frames and some minimalist road frames may not have compatible mounting points.
