Here's my ultimate commuting machine.
CIMG1188.jpg
Bionx PL500HS (500W with 10Ah 36V Lithium Mn battery)
Soma Double Cross frame
Nashbar Carbon Fork (disc brake ready)
700x23 front tire (120 psi)
700x28 rear tire (85 psi)
7sp 11-28t rear freewheel
39/53t front chainrings
clipless / platform pedals (for mtn shoes or regular shoes)
Fenders for the rain around here
Lights for night riding (not pictured)
Topeak MTX rear rack with quick mount (got pannier and basket to go with it)
Klickfix handlebar mount for detours accessories
Bell to help me be polite when passing
The whole bike weighs 48lbs. At level 3 assist: 45 miles range and top flat speed (that I can do at 90% effort) of 31mph.
Very quiet since it's a hub motor. And pedal assist (instead of separate assist switch) makes it still feel like a bicycle.
Only essential thing I'm missing is a water bottle holder. Need to find a way to get one in that space in the frame.
