I'm doing research for my first build and trying to decide between two systems, both mid-drives.
My donor bike will be a new Specialized Roll Sport, or Elite comfort bike. I'm 64 and ride neighborhood streets and bike trails for fun and exercise. I'm not commuting and do not want a throttle because they are not allowed on bike trails, plus I ride for exercise as stated.
I was all set to order a BBS02 kit from Luna until I discovered the PAS system is not torque sensing. I've read that it can give unexpected bursts of power, which is a concern to me. Sounds like it's either on, or off.
The TSDZ2 system is torque sensing and from what I've read it sounds like it would work like a factory bike that uses a Shimano Steps, or Bosch system. I have ridden bikes built on these two systems and really like the simplicity and natural bike feel. Like riding a real bike, but with stronger legs. However, I get the impression that most builders are going with BBSxx motors, plus they are less money and seam to be reliable with available parts if needed.
What is it like riding a bike using only the PAS on a BBS02 bike? What can I expect? It's a lot of money to build a bike and I want to get it right the first time. Someone told me with up to 9 levels of assist, I could find a setting that works, is that correct? I see you can add a torque sensor from another company, but it sounds complicated and you need to drill a 10mm hole through the BB, plus the added expense.
Any thoughts on helping me decide would be much appreciated.
