These days with everyone having a smart phone with all manners of apps., we don’t think there is a need for fancy and gimmicky features on the display console. We have a basic display console with LED hat display the battery capacity and interface to power the bike on power assist ( PAS) , throttle and brake with signal power cut off when braking.  This console is set on dual mode for throttle and PAS at 6 levels including off selection. The operation or controls are simple. There is an up-down button selecting 5 levels of PAS by speed and power activated with a cadence sensor. You can use the throttle to start or simple to augment your speed at any time.  There is an important advantage over torque sensor bikes that you need to push harder to get more power,  on this cadence bike you simply control through throttle and assist levels.  The upshot of all of this is an easy ride for everyone, even if you aren’t a fit rider. Battery packs,  bikes bought 17 years ago could still be fitted with battery packs on production today, and 17 years into the future you would still find the available battery packs.  This is crucial and cannot be said for many brands in the market where one could not find a replacement battery pack anymore.
