My biggest complaint about the Schwinn e-bikes -- is the high price tag. They might be nice bikes, but it seems kind of steep for a bike with a 180w front hub motor and a 24V battery. Not very powerful for that amount of money. Plus, there's no throttle! These bikes are "pedal-assist" only...
With regards to the Toshiba SCiB battery, very nice! But the bikes with this battery cost $3000! I guess if you need a 30 minute charge -- it might be worth paying the extra money. The other Schwinn models with Lithium Polymer are $2000+
Similar models from IZIP and Giant are hundreds of dollars less. But a kit will probably give you the most "bang-for-your-buck"...
