Surron Light Bee 2021

The Sur-Ron X is made in China, but the build quality suggests otherwise.

The aluminum alloy frame and swingarm are solid but light, and help keep the bike’s weight down around 100 pounds. 19-inch wheels are equipped front and rear and are shod in fairly aggressive 110/70 knobby tires. Sur-Ron branded 4-piston hydraulic brakes round out the whole package front and rear, both clamping down on 203mm rotors.

The cockpit is clean and simple. Throttle and brakes are on the right, while a digital speedometer, power mode selector, and second brake lever live on the left.

Bright LED lighting comes standard both front and rear, although both lights are constantly on and can’t be switched off.

The 2021 model shares most of its components with the original Sur-Ron, with a few notable upgrades. The latest Sine Wave controller is the most significant, boosting power by 25% and enabling regenerative coasting/braking. An improved headset, bar, and grips are also included in the package.

Most Sur-Ron X models ship with either a DNM Volcano USD8 or RST Killah dual crown front fork. These two are more or less interchangeable in terms of performance, and that’s not a good thing.

While both forks include a full 8” of travel and are fully adjustable for compression and rebound, we’ve found that they both suffer from a serious lack of damping, are prone to bottoming out under serious off-road use, and have little to no small bump sensitivity. That’s not a big deal if the majority of your riding takes place on pavement. However, if you like fast singletrack or hitting jumps, your fork will need some love.

We’ve done extensive testing on fork options for the Sur-Ron, Motopeds, and other heavier eBikes and you can read that article here. The DNM Burner rear shock is fully adjustable as well, but ultimately suffers from the same lack of damping.

Most owners opt for a dedicated dirtbike tire rather than the no-name motorcycle/mountain bike hybrid that comes on the bike.

Your options are limited by your wheel size (read more below), but since the factory rims are both the same 19-inch diameter, there are a few solid dirtbike tires out there to choose from.

The Pirelli Scorpion MX32 is a favorite from the motocross world for soft and intermediate terrain and has plenty of teeth for everything from loam to deep sand. If you’re interested in a tougher compound or prefer more of an all-rounder, the Shinko SR241 is a great alternative to the Pirelli. Opting for a Shinko also saves you money, although tracking down one in the required 2.75×19 size is tricky.

If you’re riding your Sur-Ron X offroad, it won’t take long for you to start breaking spokes and bending hoops on the stock wheels.

For aggressive riders, swapping out the stock 19” hoops with stronger dirtbike wheels is a must. Most folks will want to look into switching to traditional dirtbike sizes while they’re at it. A 21” front wheel and 18” rear will perform better offroad and give you a much larger selection of tires.
