At Leeds, we specialize in innovative e-bike conversion systems that can convert your manual bicycle into a lithium-powered electric bike that lets you go faster and farther with ease, especially when riding uphill as a hill topper with our electric bicycle kit and lithium-ion battery system.

With our 250 and 500 Watt systems, you can customize with an electric wheel and easily-installable li-ion battery systems by Panasonic and Samsung. The 250 Series takes as little as five minutes to install and the 500 Series may take longer due to more vital components such as a torque arm, pedal-assist sensor (PAS), and LCD computer.

With the front-wheel electric bike kit, there are no alterations necessary. However, some bikes may require you to file the front fork as much as two millimeters. Rear-wheel conversions are recommended for bikes and trikes that will not fit a front-wheel conversion as they require more installation time and are not necessary unless required.

Customization and More

Each of our electric bicycle kits comes with a variety of customization options, including: motor color, rim color, battery bag upgrades for the 250 Series, battery mounting options for the 500 Series, as well as optional Specialized LCD computer for measuring distance and speed for the 250 Series.

The 500 Series comes standard with an LCD computer to monitor battery power, speed, distance, and control the pedal assist power. If you require a rear-wheel conversion kit for a special bicycle or tadpole tricycle, we can also provide you with that instead of a front wheel kit. Just specify at checkout if you prefer a rear-wheel ebike conversion.

Go the Distance

Whether you want an electric bicycle kit with a motor that can take you four miles or fifty, we’ve got you covered. For shorter trips, check out our PBJ E-Bike Kit (Pocket Bike Juice) that can give you the boost you need to get over big hills. For longer trips, take a look at our Samsung Ultra and Panasonic Ultra+ electric bicycle kits. These can get you as far as fifty miles...on a single charge.
