$2000 Electric Motorcycle
|
Very interesting! My son needs a replacement for his scooter...
|
72volt 32ah battery is worth over 1/2 the total price. They need a trail version.
|
Nice! Not sure I like the style, but guess I shouldn't complain for that price.

Only 30 amp hours? My car battery holds more than that! Not that it's deep cycle or anything, but still. Also, I wish they would have the frame more open, don't be ashamed to show off the battery or motor! Covering it up makes it look like a toy.

Seconded on wanting a trail model. |
Looks very much like the electric msx 125 (homda grom) chinese clone.
The ones over here have lead acid batteries though. |

30Ah at 72v is exactly 6 times the energy of 30Ah at 12v. Many normal 12v lead acid deep cycle batteries are rated at 100Ah, but that's misleading when compared to a Li-ion 72v battery. For one, you can't use all of that 100Ah on the lead acid or it will only last a few cycles, so more realistically you have about 50Ah if you want it to last say 300 cycles. The Li-ion is probably good for 3000 cycles using all of that 30Ah. Also the lead acid is only rated that high if it is drained slowly over 20 hours, or 5 amps an hour. Drain it at the rate of an electric motorcycle and that 100Ah becomes 60Ah, then take 1/2 of that which means you really only have 30Ah but at 12v. So that battery costs about $100 and is 1/6th the usable energy and 1/10the the usable life of the battery in this scooter. That's why the battery alone is probably $1000.

Silent motorcycles, what could possibly go wrong?
