Very interested in your experience with the Horizon Greyfox - I take it you have a similar knee problem? Front hub conversions seem to come with issues, how did it work for you + what power rating did you get? How does the Scott eSub compare?
Sorry I haven't replied i have been working away
Yes I had an operation on my knee that didn't cure the problem (only a new knee will) but improved it dramatically so i converted my Dawes after much research on here i chose front wheel hub purely because it was so simple to convert, and convert back again if my knee and it would give me "Two Wheel" drive, I live in north Staffordshire very close to the peak district so it is extremely hilly terrain, and the hub sometimes struggled, however my Scott seems to take it in it's stride which you would hope it would at 5 times the cost !!!.
I subsequently put my conversion kit up for sale on this forum and have had second thoughts as it hasn't sold so i will keep both bikes just in case i need a back up
