What do I risk with an unbridled electric bike?
Electric-assist bicycles are becoming increasingly popular with people looking for a greener, more economical alternative to traditional modes of transport. However, some electric-assist bike owners seek to increase the speed of their bike by removing the manufacturer’s speed limit, also known as “unbridling”. While this may seem like a good idea to some, it can have negative consequences, putting the safety of the driver and other road users at risk. In this article, we’ll look at the risks associated with using an unbridled electric-assist bike.
What is an unbridled electric bike?
Before discussing the risks associated with using an unbridled electric bike, it’s important to understand what this means. An unbridled electric-assist bicycle is an EAB that has been modified to increase its maximum speed by removing the speed limit imposed by the manufacturer. Electric-assist bicycles have a maximum speed limit of 25 km/h in Europe, but by removing this limitation, some e-bike owners can reach much higher speeds. And this is also the case for those who use bike electrification kits, such as Tongsheng’s TSDZ2 motor(that’s ours) or Bafang’s BBS02 (which we compared with the TSDZ2 here).
Safety risks
The main risk associated with using an unbridled electric bike is the safety of the driver and other road users. Unbridled e-bikes can reach very high speeds, sometimes in excess of 45 km/h, which is much faster than most conventional bikes. This can make it difficult to control the bike, especially when cornering or braking in an emergency. In addition, other road users, such as pedestrians and motorists, may not expect an electric-assist bike to travel at such speeds, which can lead to collisions and accidents.
Legal risks
In addition to safety risks, owners of unbridled e-bikes can also face legal risks. In Europe, EAB regulations are quite strict, and owners of unbridled electric-assist bikes can face hefty fines if caught riding at illegal speeds. What’s more, in the event of an accident, the rider may be held liable if it is proven that the bike has been modified in such a way as to exceed legal limits.
In France, unbridling your bike with an unbridling kit (not to be confused with the electrification kits we offer at Syklo) can result in one year’s imprisonment and a 30,000-euro fine for offenders. In addition, the bike will be immobilized and taken out of circulation until it is brought into compliance. Since December 24, 2019, article L317-1 prohibits the use of unbridled bicycles and their circulation on public roads, more details here https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000039784406
Risks to the engine
Another risk associated with using an unbridled electric bike is motor overheating. Electric bike motors are designed to operate at specific maximum speeds, and removing the speed limit can put additional stress on the motor, leading to overheating and permanent damage.
Risks to the battery
In addition to the risks to the motor, using an unbridled electric bike can also have an impact on battery life. Electric bike batteries are designed to supply energy at a specific maximum speed, and using the bike at speeds above this limit can cause the battery to discharge faster and wear out more quickly.
Risks to the warranty
Finally, owners of unbridled EABs can also lose their warranty if the bike is modified in such a way as to exceed legal limits. Electric bike manufacturers generally offer a warranty on their products, but this can be voided if the bike is modified in such a way that it no longer complies with legal standards.
Conclusion: A false good idea
In conclusion, the use of an unbridled VAE or an electrification kit exceeding 250W (like a 1000W wheel motor on a Decathlon bike 😱) may seem like a good idea to increase your bike’s speed, but it can have serious negative consequences for safety, battery life, range and even the bike’s warranty. It is therefore important to respect the speed limits imposed by the manufacturer and not to modify the bike in such a way as to exceed these limits.
FAQs
Is it illegal to unbridle your electric bike?
In Europe, it is illegal to unbridle an electric bike or to unbridle an electric bike for a third party, as this results in a speed higher than the legal limit of 25 km/h.
How can I increase the speed of my electric bike without overriding it?
It’s possible to increase the speed of your electric bike without touching the electric motor or adding an unbridling kit. In fact, by using thinner tires, modifying the transmission or using a more powerful battery, you can increase your performance and, by the strength of your calves, easily increase the bike’s speed beyond 25 km/h.
Can I use an unbridled electric bike on the road?
No, using an unbridled electric bike on the road is illegal and can result in heavy fines.
