Swytch shows off first pocket-sized electric bike battery for DIY e-bike conversion kit

The update includes a new handlebar mount that clamps into a rigid plastic case housing the battery. But unlike most e-bike batteries that are the size of a small fire extinguisher, the Swytch battery is the size of those graphing calculators you probably used in high school trig class…

The rest of the kit is fairly standard, consisting of a basic hub motor designed to swap onto the front wheel of a bike. It hits 25 km/h (15 mph) in Europe and 32 km/h (20 mph) in the US, and it gets a standard-issue 250W label.

It’s nothing fancy, but it gets the job done and it’s how most e-bikes in the world are built. Hub motors are simple and effective, so there just isn’t much left to innovate there. Instead, Swytch focused on innovating on the battery side, which has a much larger impact on riders.
