Frequently asked questions

At eBike Parts, we believe in sharing knowledge and experience.

Over the years we have gathered a lot of information about eBikes and bicycles in general, from the mechanical to the electrical.  We openly share what we know about parts, numbers, sizes, installation and our experiences dealing with repairs and riding. 

Those of you who are members of 20×4, DIY eBikes and various MATE groups in Facebook have probably noticed us chiming in with recommendations and advice on a regular basis. We openly do this to help sales, but it also takes a lot of time, so we also wish to consolidate all the information we keep repeating into one central place for all eBikers to benefit from.

We occasionally make videos covering how-to’s and ask riders to make honest reviews of out products ans well as products we don’t even sell ourselves. 

We have consolidated out old blog and Frequently Asked Questions into this new FAQ section, and we hope to expand on the information herein as time permits.
