If you’ve read my post “BUILD OR BUY AN E-BIKE?” you know that I purchased a ready to ride Bosch e-bike and also converted one of my old bikes to a Bafang powered e-bike. After a year of riding both bikes about 1,000 miles (1.6K KM) each, which system do you think cost more to maintain?
The Bosch system was by far the most expensive to maintain. While neither the Bosch nor the Bafang systems had any mechanical or electrical problems, the Bosch system had to go to my local bike shop twice for service and the Bafang system never needed service.
Let me say that again.
While the Bosch never had a mechanical or electrical problem in the last year, it had to go into the local bike shop twice for service.
So why does a bike that has no mechanical or electrical problems need to go to the bike shop twice in 1,000 miles? Because Bosch designed their system so that a maintenance required indicator comes on every 500 miles (see wrench icon in bottom right corner of image). Once the icon comes on, it can only be reset by an authorized Bosch dealer using Bosch diagnostics software.
The joke among e-bike riders is that Bosch should change the maintenance icon (wrench) to dollar signs ($$$) because that’s what the icon really means. The bike doesn’t need service every 500 miles, the rider just has to pay to have it turned off. Perhaps it’s just an attempt by Bosch to bring revenue in to the local bike shops to help them pay for their expensive Bosch’s dongle and diagnostic software.
The maintenance of my Bosch e-bike is the most expensive of any bike that I’ve every owned. I don’t know if I would buy a Bosch system again knowing that Bosch intentionally created recurring hidden costs in their product that have no added value to the customer.
