250w Hub Motor Kit with Rear Rack Battery
The subtle and stylish matt-black mini-motor comes in either a front or rear wheel (we usually recommend a front wheel motor with this rear rack battery). The planetary geared motor is totally freewheeling, meaning there is no resistance to the normal rolling motion of the wheel.
Our wheels are built using durable double-wall rims and thicker 12G spokes, to withstand the extra weight and torque of the motor. The motor casing also includes holes to attach a disc brake rotor, if you bike has discs. All common wheel sizes are available to choose from.
This quality motorised wheel is matched with a compact 14amp controller, the brains of the system, positioned between the battery and the motor. All cables come to this hub, and are designed to be appropriate lengths for the average bike.
The controls included for engaging the motor are the pedelec sensor (mounted to the bottom bracket), and the optional-to-install throttle (thumb style as standard, or twist style available on request). Throttles are not strictly road-legal on a 250w kit, but they are sometimes popular amongst people who really need the assistance taking-off, before they have rotated the pedals enough for the pedelec to kick in.
Also included are electronic cut-out brake levers, or magnetic cutout sensors which can be fitted to existing levers, to provide a safety cutout feature when braking.
The LCD3 handlebar dashboard display allows you to adjust the strength of pedelec assistance. The display has a backlight, and it displays useful information such as battery level and voltage, wheel speed, power usage, distance travelled, and a few other handy stats.
The package is completed with a Rack Battery (options on range), which is the best solution on step-through bikes, and those with small triangles or non-straight lines on the frame. The largest battery will take the average rider at least 90kms per charge, meaning a full day-trip of leisure riding is easily possible, or often several days’ worth of commuting can be done between charges. This means the battery will last much longer than if having to charge after every ride. Small battery will give at least 50kms.
Racks can be mounted over the rear wheel of virtually any bike, presuming the bike has the mounting points on the seat stays, and down near the rear dropouts. Racks have the added benefit of being able to mount a rack-bag, which gives you somewhere to put your things, whilst also protecting your battery from full sun. And they include a bonus rear light, which is great for being seen.
We only use the top-quality battery chemistry of Lithium tri-metal (Nickel Manganese Cobalt Oxide, or NMC), which is the leading type used for electric vehicles at the moment. Read more on our batteries page.
