Every marketplace loves a buzz product. With motorcyles, it’s unquestionably the super e-bike. A super e-bike is basically a motorcycle that hides inside a lighter and simpler bicycle body. One great example of this is the new Trefecta DRT bike, a military-spec aluminium frame that’s as much a motorcycle as it is a bicycle.
Super e-bikes have zero-pedal, full-throttle modes, with speeds exceeding 40mph. They’re not quite electric bikes and not quite motorbike, while on the trail, they’re not quite mountain bikes but they’re not dirt bikes either.
The 20-inch Trefecta DRT frame is crafted from 7075 aluminium, which takes the form of aluminium blocks instead of the usual tubing. It’s a chunky design but Trefecta guarantee a fast and powerful bike which holds up to any element thrown at it. The 26-inch wheels of the DRT are made from a six-spoke carbon-fibre.
Performance-wise, the DRT possesses a 4-kW motor, a 14-speed Rohlof Speedhub and a SmeshGear transmission… Whatever that is! At low speeds, motor output is managed by a pedelec system aimed at maintaining an ideal blend of pedal assistance and battery usage.
To be honest, you want to be pedalling when you’re anywhere near the top speed of 43.5mph, so there’s also a throttle for motor power alone. The motor can send up to 184 lb-ft of torque to the rear wheel.
All the various controls on the Trefecta are controlled by a computer system mounted at the centre of the handlebars. Joes can also use the computer to choose between automatic gear shifting and electronic gear selection and to control the settings of both the suspension fork and the rear shock. The computer also shows the usual data such as speed, battery life, distance etc.
Trefecta estimates the DRT’s battery will provide enough beans for up to 62 miles without any pedalling. The battery charges in around three hours when plugged in, and a regenerative braking system adds some charging on the move.
It should be said, however, that with a $25,000 (around £17,000) price-tag, buying new batteries are going to be the least of your worries. Trefecta Mobility describes itself as “an international team of Dutch, German and Swiss engineers,” so it’s pulling in the best from around Europe so naturally the price reflects that.
The Trefecta DRT bike is more expensive than most super e-bikes available on the market. Much of this may well be down to the fact that Trefecta created its design to withstand the increased demands of military use, such as load capacity and a longer lifespan. Interestingly, the bike can also fold down into an available carry case, which is another military requirement. Regardless of price, it still looks fantastic
