My Revos kit arrived today, its fitted ready to test tomorrow.. Its been nailed to a Ridgeback hybrid cycle I've owned a short while, purchased second hand. The bike is really good and freewheels easy.. Nice light bike for such a kit. Its only for use on hills/headwind otherwise it will be turned off. I expect tyre wear ect, but that offset is ok with me. I can swap to other bikes readily if needed. My area is more very long inclines so I think this kit will be just right. I see Revos has just launched a new lightweight ebike too.
