I agree Mr Float... Electric Bikes will be a big part of our future...
I can imagine a day, not too far away (20 years?), when Petrol is Triple the current price (related to earnings).
If you spend $50 per week on petrol for your commute... Turn that into $150 (triple)... Or the option might be, ride your electric bike for 3-5 days per week, and recharge it at your desk with your boss's electricity!

Weekly fuel bill is drastically reduced.
