I installed a Grin Baserunner on my commuter bike this weekend to replace a blown up Infineon 15A controller. The difference is amazing. The rest of the system: MG311 hub, 2x LiGo batteries, Thun BB, CAv3.
Setup took me a little longer than I thought. Autotune didn't work for me initially, I had to change the startup parameters to avoid faults. I wish the manual went into a bit more detail on why I'd select hall vs sensorless running. It also doesn't list the MG311 pole count, I had to look that up elsewhere.
I didn't realize how big of a difference the silence would make. The system was already pretty quiet, but the Baserunner makes it completely silent. It really brings back one of the joys of riding a regular bicycle, which is hearing the world around you.
It feels like torque is up a bit, but this could just be the joy of the silence.
Build quality is great (like all Grin products).
Being able to overdrive the motor speed is fun. I got about 25% extra speed out of it easily. I'll probably turn this off in practice because I tend to do most of my riding in the 30-33kph range, which was the top end of my hub previously. Only using e-assist while accelerating and climbing was one of the things that allowed me to get great battery life. Having assist up to 40+kph will cause me to use a lot more battery capacity.
Suggestions: It would be great if a version was sold for use with the LiGo. These two products are really a good match. It would be simple, just sell it with Anderson connectors instead of the battery box connector, and maybe put a power switch into the case as well. I think this is just a packaging change, the core controller would be identical.
My dream Grin product is a Baserunner with the CAv3 smarts integrated so that my torque sensing BB, battery and hub all plug into one device. The handlebar mounted display could then be a lot smaller and just have 4 buttons -- the two existing CAv3 ones, and 2 buttons for AUX adjustment. This would really clean up installation and bike wiring.
