IPS 122 tilt forward on acceleration in IPS Posted February 18 · Edited February 18 by fabio70mi On 15/12/2017 at 4:35 PM, Joff said: I recently purchased a used IPS 122 on ebay. I have several Electric unicycles already (including a kingsong 18) but I figured for $ 227, why not? I really don't like the feel of it. It tilts forward a lot on acceleration. I feel like I am going up on my tippy toes to stay on. On bumpy ground, it can tilt so far forward that the front edge of the plastic fender catches on the ground and I have to hop off! On slowing down it, it tilts back. I don't mind having tilt back at high speed to keep me from going too fast, but I really don't want all this tilting back and forth at low speed. Is there any benefit to it? It does not have bluetooth. Can the motherboard be swapped with one that does have bluetooth, and if it can, would I be able to adjust the ride feel as I can on my Kingsong? I've bought IPS121 with same characteristics as your two years ago. I have your same problems. It's uncomfortable to use. Tiltback is too pronunciated, and get worse when battery is under 50% or similar. Also mine does not have BT and has 19kmh limit. And no way to change mainboard with same model doing 30kmh and BT. But going 19kmh on this wheel is quite painful. If you search, I wrote some messages about two years ago. Also I posted the procedure to calibrate the wheel. You could set some degrees forward to have lesser tiltback when you go at about 15 kmh. Anyway 227$ is also OK, it's a robust wheel, but I paid it 780€ two years ago, and it was not the latest wheel on market.
