Finally! I've loved Grin kits and felt this was the only missing piece to truly recommend their kits to others. Excited to order from again and build a new custom ebike with a SW102 for simplicity. Great work, Grin team.

I'm thinking of retrofitting an old motorcycle (think '85 Virago) with a kit. Do you think their kits would work? I'm looking to not have any bike pedals either 😅 and go around ~70kmh / ~43mph

this is great. I converted a 40+ year old road bike to a front hub unit. I've had multiple friends ask me to make one, but the cycle analyst is too user-unfriendly for non-technical people. I'll look to piece up a solution with this and try to make a turnkey bike. thanks from Ojai, California, USA

Great to see more options for displays! I would love to see a bluetooth platform one day; basically a headless CA that still handles the wiring but offloads all the data I/O to a mobile app. So many people use their phones now, or have an old spare phone repurposed as a bike speedo. Lemme know if you ever need an app developer for a project like this :)

Very cool - those are some pretty-looking displays.

It's a little more complicated than that, since the CA3 will consider you to have a "throttle fault" if it boots up and sees 1V when the min throttle input is 0V. So you first have to go to full regen to clear that fault, and then after that it would somewhat "just work" as you say.

We have them all on hand but are still working on the adapter circuit that remaps them from a 2.5V center point to a 1V center point so there is no need to change any controller settings. In principle they will work directly into a baserunner/phaserunner without a superharness, but you would have to do your own cable adapters to arrange that hookup.

where did you get the analog brake sensor from ?

I've heard the name Grin before but I didn't know what it was. Didn't concern me so just ignored it. Fwiw, I may be thinking of getting a conversion kit in the future and I will certainly check out the Grin options. 👍

A custom cable harness would be needed, but in principle that is doable by having rear wheel controller hooked up to display coms while two front mirrors just get the throttle / regen signal from the superharness.

For years I have been told you cannot change the display on an ebike because it is not compatible with the controller. Does this mean you can now change the display & still have full functionality of the lights, brakes etc. Also how much does this kit cost and can a novice install it or do you need to take it to a professional? I have a 48v 1000w motor bike & the display doesn't provide anywhere near the functionality of this one.

Lucky for you ebike stuff is way way cheaper now than it's ever been for what you get, especially used ebikes which can be had for a song these days. It's a huge bargain compared to what we had to deal with for our first ebike builds over 20 years ago. So as long as you have an interest and the skills to understand and repair things yourself you can get into this space and enjoying ebiking on a shoestring budget. Perhaps some day your circumstances will change and you can save up for some Grin Tech gear, but even if not we'll always be making free content and videos to help people understand and fix things regardless of where they get them.

IMO the original display is perfect.

"throttle needs to be independent of PAS setting". This is wrong, or at very least debatable. For any commuting/travel purpose, you always want a target maximum speed. 9 PAS levels lets you fine tune this. If you are targetting 30kph, you don't need throttle to go faster than this in emergency, and if you turn on a faster road, bumping PAS level to that road is the way. Even when in 15kph PAS setting (bike path, technical trail) throttle gets you to 0-15 just as fast, and it is much safer than just ramping up faster than this. Many crashes are related to twist throttles not letting go when starting to go sketchy. So consciously setting safe/range extending maximum speed lets you ignore your actual speed. A perfectly fine throttle design would be on/off instead of analog. Or let analog throttle control watts instead of max amps until cutoff speed reached. It is unsafe going faster than a safe speed you can let PAS determine. Variable throttle to set safety speed is not as reliable.

@GrinTechnologies

Ай бұрын

Luckily it's a simple bit setting in one of the parameters if you happen to want the throttle level to be also limited to the pas assist setting. So you can have it your way no problem while most people definitily prefer independence here.
