• Regenerative braking system
• Beautiful look
• Eco-friendly

FUTURE MODIFICATIONS

1.  higher voltage system :36 or even 48 volts  would be a lot better and keep the current draw down. I started with a 12 V system for simplicity's sake but the power was low and the current draw was high.
2. solar cell battery charger : They sell these to RV owners. Actually there's no reason why you couldn't throw a solar cell on your roof and charge the batteries all day. Imagine - this is real-world fully solar powered transportation, double today.
3. two-speed transmission : One speed for the hill and the other for the flat. Electric motors have such great torque throughout the RPM range that more than two speeds just isn't necessary unless the motor is severely underpowered. The obvious thing to me would be a hub motor with two or three speeds built in.
4. hub motor : the "hub motor" is the obvious solution for electric bikes, as used on Lee Iacocca's E-bike and the Wavecrest (which seems to have died and resurrected as the E+) and others. Heinzmann of Germany seems to still be making a variety of hub motors, as are other companies. Try Heinzmann's site www.estelle.de for some pretty interesting ideas - I guess they are now selling bikes, complete kits, motors, batteries and controllers. However, at this point they are still only about 300 watts = 1/3 HP which is about 1/3 of what they ought to be. Also, Heinzmann motors tend to be a little noisy and expensive.A hub wheel motor replaces the normal wheel hub and obviously needs no other transmission, chain, or belt which is a huge simplification - although of course this can also be a slight drawback in that the gear ratio can't be changed. 
5. lithium ion battery : Certainl y the lithium battery has the greatest potential of all the next-generation chemistries. It has the most energy per pound and is well proven in smaller applications like cell phones and laptops.
