- Nick217, on 07/15/2009, -0/+7awesome bike
- addiggt, on 07/15/2009, -0/+5I hope that something like this can reach the mainstream audience in the near future, seems like it would be really beneficial to our society.
- escottberg, on 07/15/2009, -0/+5That's the sad truth. And not only is it producing energy, but it's helping people get in shape.
- MikeChino, on 07/15/2009, -0/+4Great idea - I'm all for free energy and free bikes, but the system will need to be further monitized (perhaps through subscriptions?) to deal with bike repairs, maintenance, etc.

Think of all the cyclists... Wow, we could produce energy for whole Europe! - KLINGERATHO, on 07/15/2009, -2/+2is it very good, read http://elmundosegunklinger.blogspot.com/
- drmephesto, on 07/15/2009, -3/+0Great Idea! Its just a shame they don't teach designers much about physics. Lets look to wikipedia!
http://en.wikipedia.org/wiki/Fuel_efficiency_in_tr ...
A bike rider burns about 120 kJ per km. Lets say we recover 10 percent of that via regenerative brakes (a pretty high amount), thats 12 kJ per km. Well, a full bus (not a common occurrence), gets 0.32 MJ/passenger-km, so a half full bus gets about 0.64 MJ/passenger-km. So, we end up with 0.64 MJ/12kJ, which is about 53. That means a cyclist would have to ride 53 km on his or her bike for every 1 km of bus service, just to equal the fuel used, not including bus maintenance, oil etc.
May as well just stick to riding the bike eh?
