I like it a lot . . . BUT! The motor controller settings that come from the factory are not really optimized. The display connected to the motor controller allows 9 power settings ( or five, depending on how you set it up) but the lower settings still have too much power assist coming in at lower levels and then cutting off early just as your cadence picks up speed. The BBS02 does not have a torque sensor at the crank but rather a pedaling speed sensor. These motors like to work at high RPM so to have the power cut off when you hit a cadence of 50 or 60 doesn't make a lot of sense. Fortunately, the firmware can be reflashed with a program readily obtainable on line. You do need to purchase a special cable to hook up between your laptop and the cable going to the motor controller. There is a lot of information on the web about how to do it. Check out electricbike-blog.com. I have arrived at settings that work very well for me, with graduated power that tapers down as cadence goes up when you reach your shift point, and cuts off depending on how fast I want to go and the legal limits here in California. When I got it, there were no torque sensing units available as there are now. But the BBS02 does have a much greater power capability than the torque sensing units, so I guess it depends on how fast you want to be able to go and what your style of riding is. The other issue is that there is only one chainring and you have to choose your teeth wisely. I started with a 44 toothThe Allez was very similar from what I remember (my Trek 2300 is from late 80s). I have two ti bikes, a custom Moots YBB mountain bike (which uses the flex/return characteristics of ti as part of the "suspension") and an relatively old TST road bike from the late 90s (they made bikes for a variety of brands and briefly sold direct). How do you like the Bafang conversion?
