Our hub motor kits come in all common wheel sizes, and can replace either the front or rear wheel.  The system allows you to choose between 5 different levels of automatic pedelec assistance.  These levels are easily adjustable from the LCD screen on the handlebars.

Choose from our range of versatile and practical frame-mounted batteries, designed for balanced comfort due to their central and low mounting position.

No longer will you be limited to where you can ride.. The hills will feel flat, and the world will open up for you when you upgrade your bike with a REV-Bikes electric assist system.  Book a Test Ride – we even come to you!



Premium 250w Hub motor kit, with frame-mounting battery

The subtle and stylish matt-black mini-motor comes in either a front or rear wheel. 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 quality frame mounted battery, and there are a few different options available based on the distances you want to travel per charge. Mounting to the water bottle lugs in the triangle is ideal, as it’s good to keep the battery weight low and central, to make for a more comfortable and balanced ride.

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. Also find links to sizing templates for the frame-mounting batteries, or you can order a Battery Template Kit by mail, so that you can confirm what fits, and order your ideal battery with complete confidence that it will suit your frame.

If you are planning to DIY your e-bike build, we have a range of helpful videos to assist you, and we’ll also provide a straightforward installation manual with your kit. Or, you might like to attend one of our Training Courses, designed to help you fit your own kit, while learning the ins and outs of e-bike systems more broadly.

Our kits can electrify ANY bike, often giving a new life to your old trusty.  But if you’d prefer a brand new and shiny bike, check out our recommended bikes for this kit.

We are so sure you won’t be disappointed, we are happy to offer you a 30 day 100% Satisfaction Guarantee on this kit.. Love it, or you’ll get your money back!
