hi..i'm 250 pounds, and in trek 7300C bycicles with 500w chain engine and 2 ion lithiom batteries, i'm looking for a wheel which is very strong and can hold my weight.
will this do? Pure Tour 700c - Ultegra
Hard to say. The requirements of e-bikes are even higher than loaded touring. In Holland, rims like the Rigida Andra are pretty standard. Haven't seen them mentioned lately but SJS Cycles in the UK used to carry both the roms and complete wheelsets.
