All the bicycles on display used the same basic layout, with a rear hub mounted 200 Watt motor and a 36V, 8Ah Lithium battery in a slide out canister just in front of the rear wheel. The folding 20 inch bicycle used the same motor and batter as the larger units and is slightly cheaper. But lacks gears, a luggage carrier and full mudguards.
The idea with these bicycles is that you can pull the batter cartridge out and carry it inside to be recharged.
The battery and motor are most of the cost of such units. The bicycle accounts for about $500 of the cost.
