  • Our take on the 500W and 750W MTX Rim Ebike Conversion Kits

    An ebike conversion kit that swaps your existing rim for a powered MTX rim, offered in 500W and 750W versions. It is aimed at riders who want to electrify a road or hybrid bike without buying a whole new ebike. The 750W version gives more climbing and top-speed headroom than the 500W, but both add weight to the wheel and depend on a donor bike that fits the rim. Owners rate it well overall, though the small number of ratings means feedback is limited.

    Questions and answers

    What is the difference between the 500W and 750W versions?
