SAMEBIKE 20LVXD30 Assembly Video 

When you initially install the battery & secure the bike, there appears to be no power. HOWEVER - if you reopen the bike (as if folding it) & resecure it, you get the ‘power available’ audio advisory/beeps. Also, you must press the ‘on’ button (bottom right) on the remote TWICE to activate it (just once on the ‘off’ button - top right - powers it down). I think this an intentional design feature - to help minimise the chances of inadvertently activating the motor/throtle. Also - the battery key secures the battery in the frame (and/or unlocks it) only - the ignition circuit is separate. Great piece of kit. 🛴🛵
