The Bike, components and electrics, and support from Surface604 has been amazing! Worked with Mitchell for getting my new bike assembled and shipped - great experience. The bike arrived as advertised, professionally shipped! I'm 6'1, 200 Lbs and the M/L fits great. First trip in -5oC in Saskatchewan was great. I have the normal battery and it was depleting, but still had a lot of life left (40% charge) after 20km's/60 minutes mostly using the motor and not a lot of pedal assist. The bike rips - close to the advertised 20mph with only the motor - very little effort required over snow and ice, while feeling stable; a 'close' second to the motorcycle my wife won't let me get... The ONLY thing I would offer for others getting this bike is you'd likely want an aftermarket cup holder to cruise with! Happy riding!
