20 years ago my wife got a bike like this:
Now it looks like this:
In August I added a 9C kit from ebikes.ca. Great company to work with BTW. Also got a Ping 36V 10ampHr.
Total ebike weight around 65 lb.
I weigh 150lb and am a competitive road cyclist (this summer I did a 40K 1:00:43 ) Even being very fit, I have not been able to consistently ride my 25miles of Home-Work-Home for more than a couple of weeks, plus racing. Since I've gotten this bike I have yet to drive my car to work. ( still riding the road bike ~ 1x per week). The thing I didn't suspect is that I have stayed fit. This 1.5hr of low intensity workout has kept me pretty close to racing shape.
After about 100miles the spokes got loose and I didn't really deal with it until a around mile 700. By then there was a hop in the wheel and 3 spoke nipples were rolling around in the hub. Spent an afternoon putting on studded tires and fixing the spokes+locktight.
The only with the studs has been that I was only able to put a 35mm Nokian on the rear, due to a narrow chainstay width. So I have to really make sure there is air in the tire or I will get flats (3x in the first two weeks). No fun in cold weather.
Sans snow, it was making it about 25 miles per charge. Now I don't risk running the battery down and charge at work.
With the studs and the weigh it really is stable on snow and ice. In fact last friday in our snow storm I definitely got home faster than if I would have drove.
I'm already scheming for another build! Something a little less ugly - what I can say, I'm still a roadie.
+10K miles, rides through whatever Minnesota weather can dish out.
