RE: Lower max battery charge for hill folk
You can do it with a solar charge controller. Normally you would set the controller to output 58v 3.5 like the wall charger. If you want to charge the OW less, set it to something like 56v and it should stop charging before the OW battery is full. For a source you can use a battery as in the Carvepower portable DC charger-
Rather than a battery, you could feed the controller with a 24v power supply that will provide 9A or more like this one . That will provide enough watts for the controller to charge the OW at the same speed as the wall charger.
RE: Charger included in the onewheel
@thegreck The 4lbs is with the battery installed. These all use the same type of cell, which run about .2oz per wh. This charger comes out a bit lighter than the Chafon for 2 charges because the Chafon has a bigger housing and more hardware inside for the inverter. The big weight savings is in the choice to pack a single charge if you want rather than two.
RE: I seek out the Post Apocalyptic Landscape when I ride.
Try checking out some cemeteries. They usually have nice windy, empty roads. That's where my dad took me for driving lessons, since it is like driving on regular streets without worrying about traffic.
RE: How do you film yourself? - A selfie stick?
The Osmo Mobile with a stick is a great combo for filming the OW because of the tracking. You can draw a frame around the wheel or the lights, and the gimbal will keep the camera pointing in the right direction however you move it. Adding a wide angle to the phone also helps.
There is also a small tripod that you can mount the stick onto. You can put the OW in the frame, draw a tracking box around the wheel, and then when you ride past it will pan to follow you.
RE: low battery kickback
You are getting kickback because that is a fully dead battery, regardless of what the % says. When you get kickback, shut it off then on and ride it again until it refuses to balance. If the battery drops to 1%, do the 24hr charge. If it still says something like 7%, let it rest 10 min or so and then try to ride it again. The long recharge won't work to recalibrate unless it reads 1% when you start. If you are unsure of the battery meter, check the cell voltages. It will stay at 3.24-3.2 for a long time, but once it says 3.1 it will drop to empty quickly, maybe in a half mile.
RE: Anti-nosedive nose wheels?
You can add bigger wheels to the stock bumper by using a dremel to cut out some of the ribs on the inside. 70mm luggage wheels is a good size-
Wheels can save you from sudden deceleration caused by the nose dropping and grinding the ground. If the sudden deceleration was caused by something else like a pothole or a tree root, you are going to fly forward anyway. If you nose dive on smooth pavement because you over accelerated, you are still going to have to compensate for the floor dropping out from under your front foot, and some sudden slowing caused by resistance of the motor as it regens.
RE: Is riding with your back foot on "gas pedal" side ok?
When you raise your front heel, press down a little on your back heel to compensate. I find that solves the feeling of trying to balance the front of the board with just your toe.
RE: Onewheel app regen at 130%???
I think cell balancing might factor into it, like when a cell goes up, and another goes down it affects those numbers. I left my OW on the charger for a week while on vacation, hoping it would fix the cell balancing problems and wrong battery % readouts (it didn't). When I got back, regen said -119%.
