Many owners of electric bicycles in the UK are facing a frustrating problem: their bike motors are failing and requiring replacement more frequently than expected. This issue seems to be particularly prevalent among mountain bike riders, especially in wetter areas such as Wales. The main cause behind these failures appears to be inadequate sealing against water ingress, leading to various problems including failed bearings, failed torque sensors, and water damage to circuit boards.
The eBike Motor Centre in Hampshire, one of the UK’s leading independent ebike motor specialists, receives around 250 motors per month for repair from desperate owners searching for cost-effective solutions. Manufacturers, on the other hand, often charge exorbitant prices, with some asking up to £700 for an out-of-warranty replacement motor. This has left many affected individuals considering reverting to conventional bikes.
For example, Andy Fenwick, an ebike enthusiast from Wiltshire, was disappointed when his £5,000 Cube bike’s Bosch electric motor stopped working outside the warranty period. While a software update managed to revive it without needing a replacement, Fenwick noticed numerous reports on cycling forums about motor failures. He highlights the problem of non-repairability, with owners unable to find readily available parts from Bosch for fixing their motors. Some riders have even been advised by Bosch not to ride their bikes in wet conditions, which Fenwick finds absurd.
Water is identified as a major culprit behind these motor failures, as the latest units seem incapable of withstanding the UK’s unpredictable weather. Each time a motor fails, the entire unit must be replaced, contributing to environmental concerns due to the resulting waste. Fenwick advocates for better legislation regarding the right to repair, emphasizing the need for improved motor designs and the availability of parts for repair purposes. Unfortunately, he has received no response from Bosch after expressing his concerns.
While Bosch claims to prioritize reliability and quality, they acknowledge that technical issues can occur. They state that their later models have improved seals and bearings to protect against water and magnetic interference. However, if a major defect arises, Bosch may opt for a remanufacturing process on a case-by-case basis.
In cases where owners face motor failures outside the warranty period and are denied assistance, they may need to turn to alternative options. One such option is the eBike Motor Centre, which offers motor overhauls and repairs at more affordable prices than manufacturers. Customers have expressed satisfaction with their services.
In the meantime, the advice for electric bike riders is to keep their bikes as dry as possible and be cautious when washing them. Power washing is strongly discouraged. Additionally, owners of Bosch 4 motors should steer clear of magnets to prevent potential problems.
By addressing the issue of electric bike motor reliability and advocating for better solutions and support, riders can continue to enjoy the benefits of electric bikes while minimizing the inconvenience caused by frequent motor failures.
The electric bicycle industry in the UK has been experiencing a problem with motor failures, particularly among mountain bike riders in wetter areas like Wales. The main cause of these failures is inadequate sealing, making the motors susceptible to water damage. Failed bearings, torque sensors, and circuit boards are some of the resulting issues.
This problem has led to an increase in the number of electric bike motors being sent for repair to independent specialists like the eBike Motor Centre in Hampshire. They receive around 250 motors per month from frustrated owners seeking cost-effective solutions. In contrast, manufacturers often charge high prices for replacement motors, with some asking up to £700 for out-of-warranty replacements. This has caused many affected individuals to consider returning to conventional bikes.
One such individual is Andy Fenwick, who experienced a motor failure on his £5,000 Cube bike outside the warranty period. While a software update fixed the issue for him, Fenwick discovered numerous reports of motor failures on cycling forums. He also highlighted the difficulty in finding readily available parts from Bosch, the motor manufacturer, for repairs. Some riders have even been advised by Bosch not to ride their bikes in wet conditions, a suggestion that Fenwick deems unreasonable.
