How BikeFin Was Born

It all started when the pandemic lockdowns first hit in March of 2019. Mechanical Engineer and Founder, Liam Nelson, found himself with lots of extra time on his hands, like so many others. As a person who loves projects, he decided to convert his bicycle into an eBike.

After looking at kits for sale online for a removeable mid-drive kit, he was shocked to see that no solution existed, so he made his own. To experiment, he took existing eBike motors and batteries, and bent a simple bar of steel strategically so it would attach to the downtube and wrap around it. To his amazement, the very first prototype actually worked great. It was then that he realized the potential this new solution had. 

He believed in the idea so much that he spent the next 1.5 years working on perfecting the design full-time (at the great dismay of his Savings), and found a local manufacturer for a professional motor bracket. Then he perfected a new freewheel sprocket, as well as the electronics to run everything.

The end result is a kit that's easy to install, just as effective as current market solutions, but far more affordable.

About the 8-tooth Freewheel Sprocket
9-tooth sprocket

A unique custom-made freewheel sprocket is one of the most important pieces of the kit. A freewheel motor sprocket lets you pedal normally without the motor engaged, and then add motor power whenever you want it. However, the eBike industry currently only offers 12+ tooth freewheel motor sprockets. The problem with these is that they don't offer the right gear ratios for use with your existing rear-wheel gears/sprockets; kits that use them require an additional 44 tooth gear to be attached to the rear bicycle wheel hub, replacing the disc-brake in the process.


In order to solve this affordably and effectively, we take the widely available 12-tooth freewheel sprockets and weld a 8-tooth sprocket onto the end of it. This allows your motor to engage properly with your existing rear-wheel gears/sprockets without straining the motor. This also lets you keep your brake system untouched. Another benefit is that as you change gears depending on your speed, just like a car transmission, the motor gets the torque it needs on hills without sacrificing speed on flat ground. Additionally, because the 8-tooth sprocket has a smaller diameter than the 12-tooth sprocket, you actually get even more torque delivery from the motor.
