Fat bikes are all the rage these days, though we can’t quite comprehend why. Our limited understanding of trends doesn’t change anything to this reality however, so we’re not surprised to see manufacturer Standard Bearer Machines announcing a beefed up electric version of their Rengu line of fat bikes. The Rengu Juggernaut is a tadpole trike (with the single wheel at the back) that benefits from electric power assist, which is a more than welcome addition to a vehicle already notable for its inefficient locomotive properties.
What’s new with this model is a 2,000-watt 3-phase high torque rear hub motor. It’s powered by a 48-volt 12.5-Ah lithium-polymer battery, and linked to a 3-phase controller. In throttle mode, it’ll take the trike to an electronically-limited top speed of 20 mph (32 km/h) for a distance of approximately 20 miles per charge.
These trikes are meant to be used on sandy beaches, where the lack of electric assist would mean a much harder pedal. But the convenience of electricity comes at a price: the renege Juggernaut is $5,300!
