The Juggernaut from Rungu is not described as being a bike (or trike as the case may be) but instead gets labeled as an ATV. With twin front wheels, a 2000 watt hub motor in the rear wheel, and all of them shod in 5″ tires, it really does crawl out of the bicycle category. Designed to be the ultimate go-anywhere piece of machinery, the Juggernaut is marketed towards hunters, beachgoers, and snowbound explorers looking to decrease their carbon footprint. We covered its human-powered counterpart – the Bullfrog – a while back, which was only just barely still a bike (OK, trike), and they’ve somehow managed to make that thing even wilder. Join us past the break for the rundown on this mental machine…
Obviously lacking an internal combustion engine, the Rungu claims to be more environmentally friendly than its petrol-powered competitors and is thus also less likely to be outlawed from some more ecologically fragile areas that prohibit gas burning engines. Powered by its 2000W hub motor, the Juggernaut is capable of speeds up to 20mph in either full-electric or pedal assist modes. Just like the Bullfrog, the Juggernaut uses a 6061 aluminum frame, a pair of steel forks, and utilizes Surly rolling stock for all three wheels. The e-trike uses a Deore rear derailleur to shift through 7 cogs mounted to the motorized rear hub, and sticks with just a single chainring up front. Mounted under the downtube is a 2.5 Ah 52V LiNMC battery and controller that can also power optional e-bike lights. Twin mechanical discs slow the front wheels care of a double-pull lever, while a SRAM hydraulic brake clamps the rear wheel, somewhat surprisingly with what appear to be 160mm rotors all around. Tipping the scales at 90lbs, the Juggernaut is just that.
Offered in a deep forest green, Rungu also offers a factory-applied camouflage treatment, seen above. With the ability to very quietly cover many types of terrain, the Juggernaut promises to make a great hunting vehicle. Rungu offers several accessories to kit out your Juggernaut, like the matching camo trailer, a comfort kit with a suspension seatpost, as well as lights that run off the main battery supply.
One of the initial concerns raised was steering a trike at speed, as trikes traditionally do not lean. Rungu seem to address that with this photo. The linkage driven steering assembly uses a modified Ackerman geometry to keep both front wheels tracking correctly through turns, though at speed the entire thing IS apparently designed to be leaned like a normal two wheeled cycle, and to have the outside wheel lift. The steering configuration results in a downhill-esque 830mm effective handlebar width, which is dwarfed by the wheelbase length of over 1300mm. Intended to be equally at home in the woods, the beach, or a snowy winter wonderland, Rungu offers a surfboard towing kit as one of the many accessories for the Juggernaut.
The Juggernaut starts at $3300 and can be shipped worldwide.
