It was a sunny day, and after consulting with colleagues, we went out today to test our MC02 lithium mountain E Bike with a safety helmet on. In order to better and comprehensively measure the performance of this lithium mountain bike under various riding conditions, we specially chose an extremely difficult and bumpy road for the test ride. At the beginning, let our test riding model familiarize themselves with the route and road conditions they will pass through in order to be mentally prepared. Of course, this is also for the safety of the model during the test ride, after all, this is also an outdoor ride, unlike testing on familiar road conditions on weekdays. We have truly considered our customers and friends with great care and attention to detail. This experiment mainly focuses on whether the Ebike Motor can operate normally, whether the entire power assisted Ebike can ride smoothly during the test ride, and whether there is any occurrence of left and right swaying; Can the Lithium Battery operate normally and is there any situation where it loses power and does not work on bumpy roads. The more crucial point is whether the instrument panel can display the riding status of the electric bicycle normally during the riding process. This ride not only rigorously tested our power assisted bicycles, but also tested our modeling skills. This test ride provides a good demonstration for the testing of new models in the future.
