i have this rize x bike, bike itself is good but there are some drawbacks which i noticed after 5 months, i found my battery percentage is not accurate as i had 3-4 incidents where i was having 40% battery left and thinking i will reach home but battery jump from 40 to 0 zero within 200 meter and i had emailed Rize x about issue but they totally ignored my message as i only got one message saying team is reviewing, its been more than 12 days i still didnt get any message. Moreover, bike front wires attached to light and other wires are not durable as i found my wires has wear off coz due to many turning as wire was hard wire...i have seen many other review made by other Rize x holder about poor customer service as they hardly respond u back... even bike is good but if they dont care about customer then its horrible, i even sent video of my bike when battery died....
