Sur-Ron Ultra Bee

The Ultra Bee HP is the bike Sur-Ron built when they decided to take on full-size petrol enduro machines. 21 kW peak in Turbo mode, 511 N·m of torque at the wheel, hairpin motor, carbon fibre belt drive, 4.4 kWh battery. This is not a souped-up Light Bee. It is a different class of machine, built for experienced riders who want serious enduro performance without the noise or the maintenance.

Hairpin motor and Turbo mode

The HP designation refers to the hairpin-wound motor, an automotive-grade winding technology that increases copper density inside the stator. The result is a flatter peak power curve from 2,000 to 7,000 rpm, much better thermal management on long climbs, and a Turbo button that unlocks 21 kW for short bursts when you need to clear an obstacle or overtake. In normal use the bike sits at 18 kW continuous, which is already enough to embarrass most petrol enduros up to 250cc.

Belt drive that does not need maintenance

One of the smartest decisions on the Ultra Bee HP is the carbon fibre core belt with tungsten carbide-coated forged pulley. There is no chain to lube, adjust, or replace. After a wet day in the woods you hose the bike down and put it away. For a £5,899 machine that you might be riding on muddy UK trails every weekend, the maintenance saving is real money over the bike's life.

Range that lets you go all day

The 4.4 kWh battery (74 V, 60 Ah) is the largest on any Sur-Ron and gives this bike genuine all-day range. 115 km on the WMTC cycle, 70 to 80 km on enthusiastic mixed-terrain riding, and even 50 km if you are pinned in Sport mode the entire time. The 1.1 kW Level 3 charger fast-charges the pack in ~2.5 hours from 20 to 80 percent, so a lunch stop genuinely refills the tank.

Six ride modes including Crawl and Reverse

Eco, Daily, Sports, Crawl, Reverse and Turbo. The Crawl mode is three-stage adjustable and is exceptional for technical hill climbs and rocky going where you want absolute throttle precision. Reverse will get you out of trouble when you have nosed into a ditch you cannot push back out of. Turbo is the headline-grabber but Crawl is the mode you will actually use most.

Frequently asked questions

The 2026 Sur-Ron Ultra Bee is a proper update. Not a sticker pack. A bigger 24.5 kW motor, a higher-capacity 74 V / 60 Ah battery, 520 Nm at the wheel, and a brand new SWC (Sur-Ron Wheelie Control) that lets you pull a clean, controlled wheelie even if you have never done one before. Two new colourways: Desert Brown and Carbon Black. Everything that made the previous Ultra Bee the most capable Sur-Ron is still here. Sur-Ron just turned the dials up.

What is new for 2026

If you already own a 2024 or 2025 Ultra Bee, the 2026 jump is real:

• 24.5 kW maximum power motor, up from around 22.5 kW on the previous model. A 9% bump on paper, more noticeable than that on the bike.
• 74 V / 60 Ah lithium battery, a step up from the outgoing pack. Longer range, less voltage sag under heavy load.
• 520 Nm of maximum torque at the wheel (up from 511 Nm). Climbing torque and out-of-corner pull both stronger.
• SWC (Sur-Ron Wheelie Control), brand new for 2026. Gyroscope-driven wheelie ASSIST: roll on the throttle and the bike lifts the front to a controlled balance point and holds it for you. Essentially auto-wheelie for beginners.
• Two new colourways: Desert Brown and Carbon Black. Both proper paint finishes, not vinyl wraps.
• Class-leading basics carried over: around 85 kg kerb weight, ~68 mph top speed, hydraulic discs, DNM suspension, hairpin motor, carbon belt drive.

24.5 kW: what the extra power feels like

On paper the jump from roughly 22.5 kW to 24.5 kW is modest. On the bike it is not. The new Ultra Bee pulls harder from the moment you crack the throttle. The mid-range is where you notice it most. Out of corners, up steep climbs, when you are already moving and asking for more, the 2026 bike just delivers.

Sur-Ron has kept the controller behaviour smooth, which matters. A peakier motor without smoothing would make the Ultra Bee twitchy. Instead, the new bike rolls on power cleanly. You can ride it with one finger on the brake and your wrist relaxed.

For taller and heavier riders this is the bike you have been waiting for. The previous Ultra Bee was already capable of moving 90+ kg riders briskly. The MY26 update makes climbs and acceleration noticeably easier. If you have ridden the older bike and felt it tail off above 50 mph, the new motor pulls through that zone with more authority.

74 V / 60 Ah battery: longer range, harder hits

Two things happen when you make a battery bigger on this kind of bike. First, range goes up. Second, the bike sags less under heavy load. The motor can ask for big amps from a fuller pack without the voltage dropping off a cliff. That means the back end of a long ride feels closer to the front end. The bike does not feel tired with two bars left.

A 55 Ah Ultra Bee was already good for a proper trail day with a charger in the van. The 60 Ah pack takes that further. Expect closer to a full session before you need to plug in if you are riding mixed terrain at a sensible pace.

The charging setup is the same usable garage-friendly system. Plug it in overnight on a standard UK 13 A socket and the pack is full by morning. A 1.1 kW Level 3 charger refills 20 to 80% in roughly 2.5 hours.

520 Nm of torque: where it makes the difference

520 Nm of maximum torque at the wheel is a big number on a bike this light. For context, this is a sub-90 kg dirt bike. The Ultra Bee will tractor up climbs that would have a 450cc petrol bike spinning and bouncing.

Where you feel it most:

• Technical climbs: the bike walks up rooty, stepped sections you would normally need to launch at.
• Tight singletrack: roll on out of a bend in any mode and the bike just goes.
• Soft ground: mud, sand, and loose gravel become a traction problem rather than a power problem.
• Recovery: if you bog down, a gentle throttle pull is usually enough to get moving again.

This is the part that converts petrol riders. Once you have ridden an Ultra Bee up something gnarly without any clutch work, gear shifting, or stalling drama, going back to a kick-start two-stroke feels like hard work.

SWC (Sur-Ron Wheelie Control) explained

This is the most interesting addition on the MY26 Ultra Bee. Important to be clear: SWC is a wheelie ASSIST system, not an anti-wheelie. The on-board gyroscope reads the bike's pitch angle and the controller manages power so the front comes up smoothly to a controlled balance point and stays there. You ride the wheelie with the throttle rather than fighting it with your weight.

In practice, SWC does two things:

• Helps beginners learn wheelies safely: roll on the throttle and the bike does most of the work. Front comes up, sits at the right angle, holds there until you ease off. No more sketchy weight transfers, no more nervous launches. Just learn the throttle feel.
• Lets experienced riders show off without working at it: even on a 520 Nm bike, holding a proper wheelie at speed takes practice. SWC takes the wobble out so the wheelie looks clean every time.

SWC is essentially "auto-wheelie" for the people who have always wanted to learn but never had a safe way in. Set it up, pick your level, roll the throttle. Newer riders will avoid binning the bike teaching themselves. Experienced riders will use it for the showpiece moments. You can turn it off entirely from the dashboard if you would rather ride without electronic assistance.

Quick note for anyone confusing the acronyms: SWC (on Light Bee X and Ultra Bee) is the opposite of SAWC (on the Hyper Bee, which keeps the front DOWN for younger learners). Different acronym, different job.

Hairpin motor and the six ride modes

The HP-designation hairpin motor carries over from the previous Ultra Bee Pro. Automotive-grade winding technology, higher copper density inside the stator, flatter peak power curve from 2,000 to 7,000 rpm, much better thermal management on long climbs. The new 24.5 kW peak just gives that motor more headroom on the top end.

Six ride modes are selectable from the dashboard: Eco, Daily, Sports, Crawl (three-stage adjustable, for technical climbs and rocky going), Reverse (gets you out of trouble when you have nosed into a ditch) and Turbo (the burst-power mode that unlocks the full 24.5 kW). Crawl is the mode most experienced riders use day to day. Turbo is the showpiece.

Belt drive that does not need maintenance

The carbon fibre core belt with tungsten carbide-coated forged pulley carries over from the Ultra Bee Pro. There is no chain to lube, adjust, or replace. After a wet day in the woods you hose the bike down and put it away. For a six-thousand-pound machine that you might be riding on muddy UK trails every weekend, the maintenance saving is real money over the bike's life.

Desert Brown and Carbon Black

The 2026 Ultra Bee comes in two new colourways:

• Sur-Ron Ultra Bee Desert Brown: a warm matte brown finish that looks brilliant in the dirt. Less harsh than black, less shouty than the bright colours. Hides dust well, which is more useful than it sounds.
• Sur-Ron Ultra Bee Carbon Black: a dark, low-key satin black. Stealthy. Looks particularly good with the black anodised wheels and the carbon-effect side panels.

Both are proper paint finishes, not sticker kits. They wear well and they photograph well. Stock moves quickly on the new colourways. Get in touch on WhatsApp if you have a preference and we will reserve one for you.
