I recently installed this kit, and after much ado getting it to fit on a specialized crossroads hybrid, getting the brakes sorted, having a holiday for 2 weeks, 2 punctures to deal with.
Today, I cycled to work, 12 miles that took an hour over fairly bumpy, hilly roads and the battery died on the hour mark....
Currently it has been charging for 2 hours and it would apparently be fully charged again.
I am 6.2, 16 stone - does this tally with anyone elses experiences?
Thanks
tony
