Why square profiles, not round pipes? How strong is this frame? How much does it cost? What is the name…

In the new version of the frame, the distance between the axles of the wheels was also reduced, and the prototype geometry was optimized for size L. The…

For installation on our electric bike, I received a sample of an average Comp 17 Sporty Design drive motor with hull dimensions of 167 x 252 mm and a weight of 3.8 kg. This drive motor, based on the joint development of Japanese and Czech engineers, is capable of operating from a battery with a voltage of 36 or 48V and, depending on the settings of the software, provides capacity of 250 or 350W. Distinctive features of this drive model…

The prototype of the frame was made and, since the priority of the patent application filed earlier had not yet been received at the moment of tests start, for road tests the frame of the bicycle was partially camouflaged with a coloured tape. Before getting the sample of an average drive motor from Comp Drive, Bafang SWX 02 350W rear drive motor with a power of 350W was installed on the prototype. This drive motor worked in conjunction with a…
