OVERVIEW

The Sur-Ron is a highly engineered electric dirt bike made with only the highest quality parts. The company behind the Sur-Ron is a very successful Chinese design and engineering firm. Sur-Ron is founded by a new generation Chinese entrepreneur named "Liu Zhuo" who believes in quality and design. Sur-Ron’s previous bike, "Light bee", has earned the German Red Dot Award for its design in 2018. Not only is every detail of the bike well thought out, it looks as if a legacy power sports company took part in building it. Sur-ron spent over a million dollars in tooling to create this bike and you can see it all in the design and execution.

 

Upon visit to their assembly factory in Chongqing we were amazed by the robotic cars moving from section to section and their advanced level of automation. The test stations were equipped with high end dyno machines simulating the performance of the bike in different conditions and a large display was showing detailed results from the motor, transmission brakes and suspensions.

 

Motorino has been working for over 15 years with electric cycle manufacturers from China but working with Sur-Ron manufacturers was an all new experience. Their professionalism, integrity and the warm response helped us to successfully complete the testing and certification of their products for the Canadian market.

 

Motor

It might “only” have 6000W of power, but…that amount of power is packaged in a light weight and smart-designed frame that can take hard off-road jumps with ease. By having a large RPM reduction between the motor and rear wheel…the amp-draw demands on the battery are lowered, and the motor also runs cooler.

Axial flux electric motors have one of the highest usable power and torque densities of any electric vehicle drive motor available on the market today as opposed to the common radial flux. Because of this they can deliver the most power in the smallest package possible.

As you can see from the picture, the Sur-Ron uses a 2-stage drive. The first stage uses a belt to make the high-RPM’s quieter, and the second-stage uses a chain to manage the high torque that is being applied to the rear wheel. By having a 2-stage drive, the motor can run at very high RPM’s, which helps the input power to remain as efficient as possible, while still providing the target “wheel power” with as little motor heat as possible.

 

Battery and Charger

With high ratio 18650 battery cells, high power B.M.S., SOC battery statistics, 4 temperature sensors real-time monitoring, and host computer management process and data interface, it enables the battery to have the excellent high ratio load capacity, longer life time, and high safety and reliability.

The battery case is removable – so it’s not necessary to have infrastructure around to recharge the bike. Its light enough to take it home and plug it into the wall socket.

The battery is the most important component of every bike since it is by far the most expensive part. High energy density batteries are not cheap, and if they are cheap, they are probably not reliable. The Sur-Ron has an enormous 60v 32ah pack which is 2000 watt-hours. The battery consists of Panasonic PF cells is in a durable case that slides in and out of bike. These cells are rated for high discharge rate that allows continuously to be used at the maximum power without deteriorating their life.

These batteries also can be charged with higher current and therefore the bike comes with 10A charger and reduces the charging time in halve compare to any other electric bike that requires 5-6 hrs. The charger is also solid-state built-in cast aluminum case with external cooling fan. And because of the safe high charge current, this battery readily absorbs the high current from the regeneration function of the controller more efficiently than any other battery.

 

Controller

Sine wave controllers are the latest in brushless motor controllers which smooth out many of the rough edges of the old school “square wave” controllers, resulting in 30% less noise. The next big difference is that you will notice is much smoother throttle response off the line. Sine Wave controllers are digitally controlled and programmed, resulting in a much smoother and more predictable power curve throughout the entire range of operation.

This controller is a perfect match for the Axial flux electric motor resulting in 20% more torque than square wave/radial flux drive train combination.

This controller has re-gen coasting which comes on when coasting at speeds of over 8mph. Re-gen braking puts charge back into your battery and most importantly preserves your brake pads.

You can also turn re-gen off by hitting the "eco" switch whenever coasting and you will roll naturally without any re-gen resistance. This means you can coast like a bike when you want to.

 

Frame

The Sur-Ron frame is a masterpiece of technology. First it is designed by the same software that designed the famous birth nest stadium in Beijing, simulating the dynamic impact forces to the bike. It is formed with massive 6,000 tone press which changes the internal structure of the aluminum through the compression and forges it to withstand to three times stronger impacts of 6061 grade alloy. This also allows the total weight of the main and sub frames to be reduced to only 7.8kg! The frame is inspected by strict quality standards and dynamically tested with high pressure and sheer impacts.

The rear swing arm is also constructed in the same way to make it as light as possible, while still being strong enough to do the job of taking significant jumps. The rigidity of the frame allows high stiff shocks to be used by shortening the lengths of the rocker arm and still providing very long stroke.

 

Suspension

The Sur-Ron has a very forgiving and responsive suspension with tons of travel. The available power from a standstill is enough to get it up on its back wheel, but the throttle is sensitive enough modulate the power perfectly. The rear wheel is driven by a motorcycle industry drive chain that can deliver all of the 6000w of available power.

The Sur-Ron is equipped with DNM Volcano front suspension with RST OIL+SPRING dampening. It’s made with MAGNESIUM, and weighs in at 3.1Kg and has adjustable pre-load & compression. It’s equipped with an 8 inch travel Fast Ace for the back suspension. The shock is actuated by an additional linkage to help make the compression as progressive as possible. This means that in the first half of its compression, the swing arms response to road irregularities is very light and sensitive (which provides a smooth ride when riding fast) and the second half of the shock compression is much stiffer, which is necessary for those times when you take a big jump.

 

The Sur-Ron is designed for serious off-road riding and thousands of jumps have been performed by professional riders and stuntmen. That confirms the suspension system on the Sur Ron is rock solid.
