I purchased a Yamaha Crosscore and am waiting for the bike in my preferred size and color. In the meantime the bike shop let me take home their demo. I really enjoy it but after riding with some buddies I've become frustrated with the 20mph speed limit. I've looked at the Specialized Turbo Vado, which has a limit of 28mph, but its motor is not as powerful, neither in watts nor in torque, as the Yamaha motor and it's nearly 1K more in price. Also, most bike shops agree that the Yamaha motor is the one they see the least for repairs on e-bikes. So... I'm looking for a tuning component that will allow me to derestrict the motor. I've seen some conversation on a thread where one person said they successfully tuned their Yamaha Crosscore, however, the link they shared for the particular tuner used is now dead. Has anyone had success tuning their Crosscore, if so what did you use? Any help would be greatly appreciated. Let me say in advance, I deeply respect the perspectives and opinions of those who have no desire to derestrict their bikes, I simply do not share that opinion in regards to the bike I purchased. Thank you in advance to those who have suggestions that may help.
