My wife and I each got a TR1 Speed the week before Christmas, with Minnesota winters we didn't ride very much in Jan thru March. Not so much the cold, but all the chemcals they use around here on the roads. I now have 750 miles on mine and am loving it. I wanted a bike I could ride on pavement, gravel or ATV trails and this has been working out well for all. This is my 1st e-bike so I don't have many others to compare to except the few a test rode and a Orbea EMTB a rented at the Cayuna Lakes MTB park in Minnesota.
I wanted a bike with a more upright riding position, racks, and I am liking the fenders. The bike is heavy but I don't really notice that when I ride it. I think for me it is the most comfortable bike I have owned.
This morning I went for a 25mile ride on the paved county roads around my house and it was a great ride. Last Saturday I went on a 43 mile loop in Northern Minnesota, 7 miles asphalt, 21 gravel county roads and 15 miles of ATV trail/logging road. The bike handles it all fairly well. Tires get squirrley in the looser sand. I have only risen a short stretch on single track but I don't think that will be an issue with my riding style, I don't plan on sending it over any jumps.
Only issues is the kick stand coming loose every ride. (I did try some blue loctite, didn't help. Maybe that's why most mountain bikes don't come with kick stands) My battery charger quit working, my LBS got me a new one right away, even though he said there was a process in getting the warranty approved that could take some time, he made it his problem not mine. Also my battery was getting very hard to remove, it wouldn't release when you turned the key. LBS fixed that for me.
I took note of Law's comment regarding the pedals and got the LBS to include upgrades to flat studded MTB pedal when we bought the bikes
I did upgrade the display from the Purion to the Nyon a couple weeks ago.
I think I am getting a lot more exercise riding this bike than my old regular bike, the main reason this is more fun and I rider more often and a lot farther.
