Why choose the TOSA Bikes?
The central drive and the neatly placed battery in the frame are the domain of the most advanced electric assist bikes. The main goal of such a procedure is a very good distribution of weight and center of gravity, which has an impact on the way the bike is handled in the terrain.
The batteries can be easily and conveniently removed by disassembling the bottom flap in the frame. Removing the battery takes only a few seconds. The frame geometry is so versatile that it will suit the taste of many users. People who choose easier routes and those who like more aggressive riding will feel good on this bike.
A huge advantage of Bafang motors is very little resistance when pedaling when the bike has electric assist turned off. When we run out of electricity, pedaling is not difficult
