Hi there :)
Could someone recommend me a kit that could fit my Fx 7.7 ? I would prefer not changing a wheel and keep the relatively thin wheels. I thought about getting the Add-e but I'm not sure that could be the right choice because of the noise it produce. It's really important to me that I could ride also without elecricity near the same way im riding now. What about Bimoz? Would love to have some ideas from you guys.
