The Vancouver, British Columbia-based company claims that it's the first to bring a "pedal-assisted electric snow bicycle" to the public after engineering, prototyping, testing revisions, and obtaining approval for marketing. That said, Envo does warn that this is a preliminary DIY product for earlier adopters who need some mechanical know-how to assemble the various components.
A bogie made from CNC-machined parts can accommodate different sizes of bicycle frames. Wrapped around the bogie is the V-treaded, Kevlar-reinforced rubber snow track, which is capable of generating 220 pounds of traction and functioning on up to a 20-percent grade slope. Up front is a snowboard attached to the fork.
Power comes from a 48V battery pack with Panasonic and LG cells that delivers 1200W (just over 1.6 mechanical hp)to a brushless DC hub motor for instant acceleration and a max speed of about 12.5 mph. The unit will run for an hour unassisted on a full charge, or four hours with continuous pedal-assist.
The throttle is actuated with a switch mounted on the handlebars alongside an E-Assist display with readings for trip duration, distance, speed, temperature and battery level. A particularly cool piece of technology are the pedal assist sensors, which can tell the motor to provide a boost depending on the selected assist level (0-5).
