The Benchwheel Penny Board is a 28-in / 71cm single motor electric skateboard. The appeal is to make a battery powered penny board, actually this is the size of the Nickel board and made of wood instead of plastic.


The approx. range is 10km / 6 miles with a max. speed of 24kph / 15mph, but expect less if you don't upgrade to better quality parts yourself.

== 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 ==
== Upgrades ==
* Front and back LED ligths, mounts, reflectors
* Front and tail LED light mounts/reflectors - be seen
* Belt cover - 3D printed
* Belt cover - 3D printed to prevent grit coming in-between the belt and pulley
* Current sensor, ESP current and voltage display
* Current sensor, ESP current and voltage display - battery health
* On-board web server with current and voltage chart history on OLED display/wireless OLED
* On-board web server with current and voltage chart history on OLED display/wireless OLED
* External 2A USB power socket
* 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
