The problem is Alta recently folded and assets just auctioned off. There is a cult following because they are such great bikes. I think Bombardier bought the assets. Someone will revive it or use the technology. Stielow's idiot friend Ryan that wires his cars worked for Alta and hooked me up with a test bike. I think it makes about 42 hp, no transmission, 14000 rpm, 4 different power levels to select from, no gas tank, no oil to change, no air cleaner to service. The battery pack is denser than Tesla's. Totally sealed so you can actually drive it under water for maybe 20 minutes ?
