I purchased two ebikes CycVerve ebikes from Cycrown. The bikes were delivered to my front porch about 10 days after order (California to Central Kansas about 90% assembled. All the tools to complete the ebikes assembly came with this purchase. Instructions that came with the bikes made the assembly quick and easy. After riding one of the two ebikes for over 20 miles I notice the motor started to make a grinding noise when accelerating. I contacted cycrown support and informed them as to the motor issue. I was asked to video the problem which I did and I got an immediate response from warranty support that they would be replacing the motor movement. I was impressed with Cycrown’s support and response in that they immediate responded to my questions and did not waste any time remedying my future repair.I chose do repair my ebike myself rather than to take it to a ebike repair shop. Cycrown Support provided all the instructions how to repair, which was fully explained by email, and Cycrown video. In addition, there are many free YouTube repair videos on line that provide additional information, if needed. My only problem with the motor movement transfer repair came in removing the torque headed screws that is necessary to gain access to the original motor core. Everyone warns of being very careful with removing lock tighted T screws because the head can strip out. I used an T screw bit with a socket wrench tool and couldn’t remove any of the screws that were lock tighted in without the screw heads more the not stripping out with the amount of force that I was using. I found out the only way was to use a power tool with torque bit to remove the screws and using a socket wrench with torque bit will not work. With using the power drill procedure, every lock tighted screw was easily broke loose and was easily removed with no additional damage to the screw heads. One additional note is to be sure to observe the original positions of the slip washers when taking the movement apart so they are correctly repositioned in the movement transfer. I am pleased with Cycrown’s after purchase service.
