Q-Matic is mounted and running great! Hit 25 MPH and was still accelerating but I have a very short street book-ended by a stop sign and stop light. Rear tire is too wide though and chain is skipping off the tires sidewall. Left side 170mm crank is too long and I had to cut it down for now. Ordered a 152mm crank arm and two 24"x2.10" tires. I love the 24x3's but I can't have the chain bouncing off the sidewall. I'm crazy but I'm not that crazy. 25 MPH on a bike feels like 60 and the hydraulic disk brake is working overtime to slow me back down.
