Probably the most visually-prominent feature of the Voltinator is its integrated structural battery box. In the version that we saw at the North American Handmade Bicycle Show last weekend, that box contains a 44-volt battery pack. Because the compartment is so large, however, there's room for do-it-yourselfers to upgrade.
The battery powers a 750-watt rear hub motor, making possible an electronically-limited top pedal-assisted speed of 20 mph (32 km/h) and a range of approximately 35 miles (56 km). Speed demons should note that there is another model that incorporates a 96-volt battery and a 5,000-watt motor, however, to reach a top speed of 50 mph (80 km/h). Additionally, there's an output port for charging devices such as phones.
The control panel features a Raspberry Pi 3 microcomputer running Linux, which displays data such as battery charge level, estimated range and current speed. Company president Kevin Risse suggested to us that hands-on types could also wire in peripherals such as a rear-view camera.
Made from billet machined aluminum, the frame has an interchangeable rear end that can be swapped out depending on the desired wheelbase, wheel size, and whether or not the buyer wants rear suspension. All told, the complete bike weighs 76 lb (34 kg).
If you're interested in getting one, the Voltinator sells for about US$5,000. Should you have a motor, battery pack and various bike bits already on hand, however, you can just buy the frame for $3,000.
