Whether you’re hitting the trails or cruising urban paths, understanding the SurRon Ultra Bee top speed can help you decide if it’s the right ride for you.

What is the SurRon Ultra Bee?

The SurRon Ultra Bee is an electric off-road motorcycle designed for adventure seekers who want the thrill of dirt biking without the noise and emissions of traditional gas-powered bikes. Manufactured by SurRon, a company known for pushing the boundaries of electric mobility, the Ultra Bee bridges the gap between lightweight pit bikes and full-sized motocross machines.

Key Specifications of the SurRon Ultra Bee

To truly appreciate the SurRon Ultra Bee top speed, it’s essential to look at its overall specs. These details not only highlight its engineering but also explain how it achieves its impressive performance.

• Motor and Power: The Ultra Bee is equipped with a permanent magnet synchronous motor. Depending on the model, it delivers peak power ranging from 12.5 kW to 21 kW. For the standard version, expect around 5,600W, while the HP (High Performance) variant ramps it up to 21 kW. This translates to explosive acceleration, with 0-50 km/h times as low as 2.3 seconds in some tests.
• Battery: A 74V lithium-ion battery is standard, with capacities varying from 55Ah to 60Ah. The HP model boasts a 60Ah pack, providing up to 4,440 Wh of energy. Charging times are efficient, taking about 2.5 hours for a 20-80% charge using a fast charger.
• Weight and Dimensions: Weighing in at around 187 lbs (85 kg), the Ultra Bee is lightweight yet sturdy. It has a seat height of 35.8 inches, ground clearance of 12.5 inches, and a wheelbase of 54.3 inches, making it maneuverable on tight trails.
• Suspension and Brakes: Front and rear adjustable suspension with 240mm travel handles rough terrain effortlessly. Four-piston hydraulic disc brakes provide reliable stopping power.
• Tires and Wheels: Knobby 19-inch rear and 21-inch front tires ensure grip on dirt, mud, or gravel.

These specs combine to create a bike that’s not just fast but also versatile for various riding conditions.

Diving Deep into the SurRon Ultra Bee Top Speed

Now, let’s get to the heart of the matter: the SurRon Ultra Bee top speed. According to official claims and independent reviews, the standard model tops out at around 50-56 mph (80-90 km/h). However, the 2025 HP version pushes this boundary further, achieving a maximum of 59 mph (95 km/h) under optimal conditions.

In real-world testing, riders have reported consistent speeds in the mid-50s mph on flat surfaces, with some modifications allowing for bursts over 60 mph. For instance, one YouTube review showcased an upgraded Ultra Bee hitting 80+ mph, though this involves aftermarket parts like enhanced controllers or batteries. The bike’s torque—up to 324.5 ft-lbs at the wheel—plays a crucial role in reaching these speeds quickly, making it feel even faster than the numbers suggest.

It’s worth noting that the SurRon Ultra Bee top speed can vary based on the riding mode. Options like Eco, Daily, Sport, and Turbo (in HP models) allow you to balance speed with battery life. In Turbo mode, you’ll hit the top end faster, but at the cost of range.

Factors Affecting the SurRon Ultra Bee Top Speed

While the specs give a baseline, several variables influence the actual SurRon Ultra Bee top speed you experience:

1. Rider Weight and Load: Heavier riders (e.g., over 170 lbs) may see a slight dip in top speed, as noted in user forums where one rider reported capping at 44 mph with a low battery.
2. Terrain and Conditions: On flat pavement, you’ll max out easier than on hilly or off-road paths. Wind resistance and surface grip also play roles.
3. Battery Charge Level: As the battery depletes, power output decreases, potentially reducing top speed by 10-20%.
4. Tire Pressure and Type: Properly inflated knobby tires optimize speed; switching to street tires can boost it further for on-road use.
5. Temperature: Cold weather can reduce battery efficiency, while optimal temps (around 70°F) yield the best performance.

Understanding these factors helps riders maximize their SurRon Ultra Bee top speed safely.

Real User Experiences and Reviews

Riders love the SurRon Ultra Bee for its silent operation and instant torque, which make achieving the top speed feel effortless. One reviewer praised its handling on motocross tracks, noting how the bike’s lightweight design allows for quick acceleration to max speeds without fatigue.
