The Surron Light Bee and Ultra Bee electric motorbikes have become hugely popular with off-road and urban riding enthusiasts. Their lightweight design, eco-friendly propulsion and great performance attract both amateurs and more experienced riders. However, one of the most frequently asked questions by users is: how do I extend the range of these machines? In this article, we take a look at the standard range parameters of both models, battery upgrade options and additional modifications that can affect the distance covered on a single charge. All given in a simple, accessible way, with a touch of expert knowledge and practical advice!
Surron Light Bee and Ultra Bee coverage – what do they offer as standard?
Before we get into ways to increase range, it is worth understanding what we are starting with. The Surron Light Bee and Ultra Bee differ in battery and performance, which directly affects the distance they can cover.
Surron Light Bee – lightweight and range as standard
The Surron Light Bee is equipped with a 40 Ah battery. Under ideal conditions, i.e. at a constant speed of 40 km/h, it allows you to drive up to 75 km. However, when you push the gas to the limit and reach a top speed of 75 km/h, the range drops to 30-40 km. Why? Higher speed requires more energy and the battery drains faster. It’s a classic principle in the world of electric vehicles – the faster you drive, the shorter you can enjoy the ride.
Surron Ultra Bee – bigger battery, more potential
The Ultra Bee is a more advanced model with a 55 Ah battery. At 40 km/h it offers an impressive range of up to 140 km. However, in tougher conditions – for example off-road or at higher speeds – the distance drops to 70-90 km. This is still a great result, but for those who want to explore even further afield, the standard battery may be a limitation.
Battery upgrade – the key to greater range
If the standard range doesn’t satisfy you, replacing the battery with a more capacious one is the simplest and most effective way to increase it. City Lion offers plug-and-play batteries that fit both Surron models perfectly. Let’s take a look at how these upgrades change the capabilities of the Light Bee and Ultra Bee.
City Lion 68 Ah battery for Surron Light Bee
Replacing the standard 40 Ah battery with the City Lion 68 Ah model is a real game-changer. What do you gain?
- At 40 km/h: Range increases to around 128 km. This is almost double the standard distance!
- At 75 km/h: You can expect 55-60 km, which is a marked improvement on the 30-40 km in the original.
A battery like this is a great option for those who like long rides at a leisurely pace, but also aren’t afraid to speed up sometimes. The extra 28 Ah of capacity makes a huge difference, and installation is trivial thanks to the plug-and-play system.
City Lion 104 Ah battery for Surron Ultra Bee
For Ultra Bee owners, City Lion has prepared an even more powerful option – a 104 Ah battery. The results are spectacular:
- At 40 km/h: The range goes up to 265 km. That’s a distance that allows you to go on day trips without worrying about charging!
- Off-road or at higher speeds: You can expect 132-170 km, with an average of around 150 km.
A battery like this is a dream for anyone who wants to maximise the Ultra Bee’s potential – both on the road and in rough terrain. Higher capacity also means more flexibility – you can ride more aggressively without losing range as quickly as with the standard.
How does driving style affect range?
While replacing your battery is the quickest way to increase your range, don’t forget that your driving style makes a huge difference. Here are some tips on how to squeeze more miles out of any battery – standard or upgraded.
Maintain a constant, moderate speed
As the data shows, driving at 40 km/h achieves maximum range on both models. Rapid acceleration and high speeds use up the battery at an express rate. If you care about distance, stick to a relaxed pace – it’s simple, and it works!
Avoid frequent starting and braking
In the city, where you stop at traffic lights every now and then, the battery wears out faster. Every start from scratch requires a considerable amount of energy. Plan your routes to avoid unnecessary stops – a smooth ride is your ally.
Adapt to the terrain
Off-road, the range will always be less than on a flat road. Hills, mud or sand force the engine to work harder. If you’re riding off-road, consider a higher capacity battery, like these from City Lion – they’ll give you more comfort and reassurance.
Additional modifications for longer range and better performance
In addition to batteries, there are other ways to improve the range and overall driving experience. In the Surron modification category you will find accessories that may interest you.
Torp TC1000 controller – more power, but what about range?
The Torp TC1000 controller for the Ultra Bee increases the motorbike’s power output to 58 kW, and 42 kW for the Light Bee. This is a huge leap in performance, but it comes at a price – more power can shorten your range if you ride at full throttle. However, if you combine the driver with a higher-capacity battery, you gain both dynamics and distance.

Rapid charging with 72V 15A charger
Charging time is another aspect that affects convenience. The 72V 15A charger speeds up the topping-up process, which is particularly useful if you have a high-capacity battery such as 68 Ah or 104 Ah. Shorter charging intervals mean more time on the road!
Why invest in modifications?
Increasing the range of the Surron Light Bee and Ultra Bee is not only a matter of convenience, but also a way of adapting the motorbike to your needs. Longer rides, less stress about the battery and more freedom all make riding even more enjoyable. Products from City Lion, such as batteries, controllers and chargers, are designed with Surron users in mind, so you are assured of compatibility and quality.
Who are these improvements for?
- Lovers of long trips: The 68 Ah and 104 Ah batteries are the ideal choice for all-day adventures.
- Off-road fans: more capacity means less restriction in difficult terrain.
- Urban users: fast charging and driving style optimisation will allow you to dash around town without worry.
Bottom line – how far will you go with Surron?
The Surron Light Bee and Ultra Bee are fantastic machines, and their range can be significantly increased with the right modifications. The standard batteries (40 Ah and 55 Ah) offer a solid base, but swapping to City Lion models – 68 Ah for the Light Bee and 104 Ah for the Ultra Bee – opens up a whole new range of possibilities. Add a Torp TC1000 controller for more power and a fast charger, and your Surron becomes a vehicle without compromise.
