Looking for enhanced power, increased torque, and extended top end performance? Look no further than the Sur Ron Ultra Bee Sotion Motor.
Whether you're conquering mountain peaks or cruising on the asphalt, the Sotion Motor delivers an exhilarating extra surge of power.
Meticulously crafted for the Sur Ron Ultra Bee, this motor features a larger rotor, an expanded stator, and groundbreaking IPM technology. It's not just about gaining power; it's a revolutionary efficiency overhaul.
Focused on enduro riding, the MTO Racing Edition excels in various situations, from torque demanding uphills to high speed sprints exceeding 100km/h, to hard enduro sections requiring instant torque bursts.
After extensive testing with various controllers, we requested Sotion to make some winding adjustments for improved performance distribution. In simple terms, it heats up less at low speed, offers a more linear torque distribution, and will deliver an electrifying experience every time you pin the throttle.
Now, let's talk power, and we mean serious business:
Numbers might seem mundane, so let's put it in perspective: with the Ultra Bee weighing around 90kg, riding with the Sotion motor means having 1HP for 2.06kg. Just for comparison, the KTM 450 SX-F has 1HP for 2.02kg (but whith a very narrow powerband inherent to petrol engines). Not bad!
Buckle up because when you pin the throttle, it's not just going to pull; it's going to pull hard, really hard! Get ready to be swept away in a symphony of raw energy that transcends the ordinary and propels you into the extraordinary.
When it comes to choosing between the Hall sensor and the Encoder, we’ll skip the overly technical stuff to keep things clear.
Simply put, the Hall sensor has the advantage of being supported by all controllers and being more reliable thanks to a simpler design.
On the paper it's slightly less precise than an encoder, but let's be realistic: encoders are often used in precision CNC machines, we don't need nanometer precision here. All the more that most controllers switch to sensorless beyound 5-10km/h.
This is the very reason we chose Hall Sensor as a default. Now if Encoder is your cup of tea, we keep them readily available and switching is litteraly a 30sec task that could be done by a 6 year old.
Compatible controllers include: the Nucular, the Torp TC500 (from 2023), the TC 1000, the EBMX X9000 and the Far Driver.

We're working on it, currently have good results on our testing hardware. Shoot us an email if you want to be part of the beta testers!

Hey Chris, As discussed with David from Eduro, UB motor could fit! It's 142mm spacing between the mounting points.
Quentin
We have it in stock and I do recommend going with Hall sensor as it's better supported 🙌
Got word from Torp 6-19-2024 that there are updates to the TC1000 coming next week that will include the support of encoder for the Sotion 16kw motor. Before only Halls was supported.
Quentin
Hey there! We don't charge VAT to Norway fo course. I'm not 100% sure whether the Motor will be plug and play with the stock controller though. Yes you can switch from hall sensor to encoder and reverse, so in any case, there's no lock-in 🙌
Quentin
Clearly one of the best, there are probably other options but that's the one we're running and that pulls really hard without heat issue 🙌
