Benchwheel Penny Electric Skateboard

The Benchwheel Penny Board is a 28-in / 71cm single 1000W motor electric skateboard. It's what you would call a Chinese electric skateboard. The appeal is to make a battery powered Penny Board (the plastic boards), actually this is the size of the Nickel board and made of wood instead of plastic.

The range is 8km to 10km / 5 to 6 miles with a max. speed of 24kph / 15mph, but expect less if you don't upgrade to better quality parts yourself. Retail price 349 USD + shipping. Get a good price at aliexpress or alibaba.

Remote operation

The instructions doesn't cover the operation of the remote properly. Albeit being a simple remote, there is a trick to switch between full- and half-speed.

Power on/off:

Press and hold the top-red button for 2 seconds to turn on or off the remote

Change between full and half-speed mode:

This can only be done after powering on the remote and before touching the joy-stick
Press the top-red button momentarily and the LED indicator on the remote will switch between L (half-speed) and H (full-speed)

After using the board, the only way to switch speed mode is to turn off and on the remote, then change mode

Pair remote and board:

Turn both remote and board off
Press and hold the power button on both the remote and board for 5 seconds until two beeps are heard
Turn both off and on again to use the now paired board

The controller comes pre-paired but if you hold the power button accidentally too long it can loose the paired connection.

Change between forward and reverse direction:

Power on the remote and board
Move the joy-stick forward once to engage the motor
Now, momentarily press the top-red button to change between forward and reverse direction

This can be done while using the board, stand-still or in motion.

Check board battery level:

Power on both the remote and board
Look at the lower three LED indicators on the remote, this indicates the battery capacity left
All three 100%, two 66% left, one 33%, blinking 5-10% left

When the remote starts to beep and the lower red LED starts to blink, it is giving you a warning that the battery is about to run out and needs to be charge immediately. The controller limits the max. speed. Under a 1km/mile left of juice.

Upgrades

Front and tail LED light mounts/reflectors - be seen
Belt cover - 3D printed to prevent grit coming in-between the belt and pulley
Current sensor, ESP current and voltage display - battery health
On-board web server with current and voltage chart history on OLED display/wireless OLED
External 2A USB power socket - to charge the remote and phone
Replace rear truck with dual motor and extra speed controller - more speed and acceleration
Swap over to HTD-5M 15mm 53T belt and 15-36T (or 15-40T) pulleys - for more efficient drive train
