I have two Bulls Ebikes with Bosch systems for the wife and I to tour around together, but I still like the freedom and feel of my road bike experience. Now that I am 69 it has been the perfect reuse of my trusty 2013 Trek 1.2 bike with a quick release fork and conventional crank and internal bearings. It was an easy install per the good, provided instructions and with great customer service here in the US for a few technical questions and ordering an extra battery. Responses were always within one day given the time difference. I think it’s the best Ebike conversion around and a great value to add to a decent framerset. I think it basically performs about as good as a $4,000 Scott Addict with a Mahle X35 250w rear hub motor. With some good peddling effort and good gears, the lowest assist level helps get me up my 1000’ climbs with great battery range with no-power descents, and it still feels like my same bike with no noticeable motor resistance. Maybe I would like a fully integrated electric assist road bike someday, but for now it is all I need to keep on riding. I have a few other bikes, and friend’s bikes to Swytch. Thanks
