Fluid FreeRide has informed us that they are investigating brake failures related to the Mercane WideWheel, of which they are the exclusive distributor of in the United States.
They are contacting customers who purchased the WideWheel and asking them not to use the scooter until their investigation is completed.
Below is an excerpt from a letter that is being be sent out to all Mercane WideWheel owners.
Electric Scooter Guide will continue to follow this story and provide important safety updates as we learn of them.
Recently, a few of our customers have experienced a problem with their brake caliper which led us, as the exclusive distributor of Mercane’s product in the US, to trigger an urgent investigation at Mercane and their caliper supplier.
The initial results of Mercane’s investigation with the caliper manufacturer indicate that a small share of calipers may have been assembled incorrectly over time and might, under certain circumstances, not perform as intended. We have been told that the caliper manufacturer, a leading Chinese supplier of brakes, whose calipers are installed on many different scooter models, is conducting an urgent investigation into the caliper assembly process.
The observed malfunction of those faulty calipers occurred when tightening the brake by only using the barrel adjuster (instead of also using the brake pad adjustment screws), thereby significantly reducing the travel distance of the caliper arm and causing the internal caliper mechanism to fail when pulling the brake lever.
As of today, we cannot be sure that this is the only reason a faulty caliper would fail. Given the potential serious consequences of a malfunctioning caliper, we have no choice but to ask you NOT TO USE YOUR WIDEWHEEL ELECTRIC SCOOTER until we have identified the exact cause and how to solve the problem.
The currently debated options range from asking you to stress test the brake following clear instructions in order to identify those faulty calipers, to replacing all calipers in circulation.
We will have another update for you by Tuesday, Sep 10th.
I understand how disruptive and disappointing this is for you.
We are in this together. Please rest assured that fluidfreeride first and foremost has the safety of its customers in mind. Together with Mercane we are urgently working on a solution to get you up and riding safely again.
