I'm new to this board and new to e bikes. I just added a bionx pL350 to my Trek 7200 and I'm loving it. I decided to buy the kit when I changed jobs and cycling to work changed from a 9km ride with a single hill and a change in altitude of about 30m to a 14km ride with several steep hills to cross and an overall altitude gain of 70m. I tried the ride a few times without bionx and found that it took almost an hour and left me wiped. Instead, I would ride my bike about 9kms then shower at a gym and ride the subway the rest of the way. Getting the bionx kit has made it possible for me to the ride daily with relative ease and complete the ride in about 35 minutes.
My route is mostly along ravine paths which are bumpy, muddy and until this week, snowy in parts. Despite the elements and bumps, the bionx kit is performing flawlessly so far. None of the glitches that others have spoke about, but it is early days. The kit is of the older style with the four pin connector. I haven't made any changes to the configuration and I don't think i'll bother. I do think it would be nice if the system helped me maintain those speeds of 45km as the curve starts to point upwards instead of not pitching in until I'm back down below 32km, but so far, that's my only complaint.
