I made my purchase of an FX2+ at the end of July and have covered 2500km so far. I had been doing conversions of friends and my own bikes using either Tongsheng mid drives or Bafang 310/311 250 watt hub motors. My 2 favourite bikes were, and still are, hub motor driven using Grins Cycle Analysts and 24 pole cadence sensors.
I made the mistake of looking at bikes in a Trek store, and saw this gorgeous viper red e-bike with torque sensing bottom bracket and almost no visible cables. A quick ride around the block and that was that! After all it was my birthday.
I soon came to realize that things were not what I had expected. A lag of almost a complete revolution of the pedals before anything happened and then power came on in a big rush, far more than I needed in level one assist. Using the Hyena app I reduced assist to 5% (no difference) and subsequently to 1% (no difference). Discussed with dealer who used the Hyena diagnostic tool and decided along with Trek that the torque sensor should be replaced. This was done and guess what - it behaves exactly the same! By the way, in mid and high level assist I can ghost pedal from 10 to 30km/hr. Obviously cadence only.
I give up. Most of my riding on the level I can handle without assist. I just switch it on as required. The way that I ride allows me to easily achieve 100km range.
It’s disappointing, but it’s a lovely looking bike. By the way, if you have this bike or the dual sport, mark the motor cable connector pair with a spot of white paint to make reconnection easier.
