YouTube

The beauty of YouTube is not the conspiracy theories or false information spread by mindless drones.

The main one for me is videos of how to make, assemble or fix virtually anything. 

Yesterday I decided to calibrate the controller on the e-bike, but the instructions were useless. All they did was show you how to access the parameters, but nothing about setting them and what the settings actually mean, Here's where YouTube became invaluable. 

Two critical parameters were that for setting the size of the wheels (essential to get an reasonably accurate speed and distance reading) and another that disengages the throttle when stationary (which prevents the bike accidentally lurching forward when stationary).

Despite being ordered as a 29 inch setup, the display was factory set to 26 inch, meaning the distance and speeds I assumed the bike to be doing are wrong, but that has now been corrected. Similarly, the throttle was set to engage immediately, even when stopped.
