Ariel Rider's latest creation is purpose-built for blasting through unforgiving terrain. The Mudd 72V packs enough power to rank it among the fastest ebikes you can buy – and it's got off-road cred to boot.

The brand's been making powerful off-roaders for a while, including the mighty Grizzly we covered a few years ago. The Mudd takes things up a notch with a lightweight build and top-notch componentry for even more speed.

Powering this beast is an oil-cooled hub motor rated for 3,500 W and capable of 8,000 W under pressure. It's housed at the center of the 24-inch rear wheel, and mated to a 95-A sine-wave controller for more than 243 lb.ft (330 Nm) of torque. That's enough to get this up to speeds above 65 mph (104 km/h) with instant acceleration – going from 0-20 mph (0-32 km/h) in just 1.6 seconds.

As you'd expect with that kind of firepower, it's only allowed off-road or on private property.

The Mudd also gets a 72-volt 39-Ah battery, which should get you between 80-120 miles (about 130-195 km), depending on how hard you ride it across its three modes that adjust power delivery. That battery is center-mounted, so you can expect stability at high speeds and more responsive handling than with a weighty battery mounted up on the rear rack.

With that sort of range, you should be able to cover a lot of ground. Switching between the Mudd's torque sensor and cadence sensor modes lets you go from powerful pedal assistance to smoothly munching miles without having to put in a lot of work.

This bike also features also gets fat 24 x 4.0-inch tires, 220-mm four-piston hydraulic brakes, and a four-link 6061 aluminum alloy frame with an MTB-like linkage system that'll take a beating like a champ. You'll also find a DNM air shock and through-axle fork with 100 mm of travel working to make your ride comfortable across all kinds of road surfaces.

That's a whole lotta bike at any rate. Ariel Rider has it listed at US$3,999, but it's currently available to pre-order for just $2,799. At that point, it's a lot more affordable than some other ebikes that can go as fast, including the Revolution models from Hi Power Cycles which start at around $11,000.

I wonder, sadly, how long until some idiot rides one on a public thoroughfare and gets themselves or someone else killed.

"ebike"? More like illegal e-moto.

Thanks for reporting this impressive machine.
For the mountainous terrain we have, regenerative braking really does extend mileage. This unit seems to not have regen.
Just because it has a dangerous top speed, doesn’t mean it is used except to see if it can really do it. Funny enough, their web page has a neato miles/speed estimator. 31 miles per hour gives 50 miles. 15mph makes 185 miles, while 65mph yields 11 miles; a stark reminder how fighting air really takes the juice
This agrees with my experience with our 50+mph rear hub kit on a 90’s Specialized S-Works. Yeah rim brakes are not ok for higher speed, but the torque is a blast for our steep country.

I never understood why you would want to change from cadence to torque and back again why not just keep it on torque sensing?

It’s just a matter of time before society will require licensing and insurance for all e bikes, because there’s always someone to test the absolute maximum before legislation makes it manditary.
