Quadbikes

The Exoquad four-wheeler is designed to let wheelchair users independently explore the gnarliest of outdoor environments. And while it packs multiple motors, it has an unpowered sibling that's made for no-holds-barred downhill descents.

Just like their automotive counterparts, gas-powered quad bikes (aka ATVs) aren't exactly poster children for the green movement. That's why we're seeing an increasing number of electric models, the latest being the carbon-fiber-bodied Equad.

While cargo ebikes can be used to haul goods around town, a pedal-powered small van would better suit inner-city delivery businesses. Germany's Antric has just launched a four-wheeled cargo box that's rated to haul a full Euro pallet per trip.

Pedal-pounding mountain bikers shouldn't get to have all the fun. The Manul 4x4 Handquad is designed to bring a similar multi-terrain riding experience to wheelchair users, with an assistive boost from an electric motor.

Take one dynamically unstable, highly dangerous vehicle platform – the venerable quad bike – and juice it up with more than a thousand horsepower, and you've got an absolute widowmaker. But is it the ultimate widowmaker? Let's assess the competition.

Instead of making a caravan to tow via bicycle, Flevobike integrates ebike and camper together, creating an ingenious pickup camper-like pedaled micro-RV. The tiny electric camper includes a solar charging system for off-grid camp and e-drive power.

Just because the €7,000 Ami is now available to buy doesn't mean Citroën has given up parading it around as a concept car. This time, it explores how the Ami could transform into an adventurous little off-road buggy.

There are supercars and superbikes ... Why not a superquad? Slovakia's Victor Engler couldn't think of a good reason, so he went and built this 850 horsepower V10 monster, which he says tops out at a ludicrous 350 km/h, or 217 mph.
