Grin Kits with Modern Display? No Way! Introducing our SuperH Conversion Platform

[@grimmsheldon]

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.

[@CanuckBacon]

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

[@CamiloSantana]

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

Brainy stuff! You guys have really thought this through. Thanks.

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 :)

It's been started and aborted many times over the past 15 years, but perhaps next one will be the charm! ;-)

[@strepto42]

[@RaglansElectricBaboon]

Very very good. The CA is awesome but it looks so very old school. This SuperH will make selling good Grin stuff much easier. With all that said it still can't touch my favourite setup -- no display just a toggle switch on the battery ;-) Moving on from being a smartarse, I think there could be a market for a bluetooth version of the Super H meaning you can see all the detail on your phone if you want it but you can just ride your bike without a display most of the time.

Fantastic!...onwards and upwards…

[@brendentrethewey8154]

The boring stuff is the best! When is the Bidirectional twist throttle going to be made available ? (the lower one at the 3:12 mark) Will they work without the super harness?

[@GrinTechnologies]

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.

Hi, do you sell to the UK at all? And yep, been waiting for some time for this.

good to know !

[@christopherheijkers5325]

where did you get the analog brake sensor from ?

[@NicholasMackris-iq5uh]

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.

[@GrinTechnologies]

Generic system display compatibility is a total nightmare to navigate In some cases they are fully proprietary, in others they use one of mauve a half dozen Chinese "standards" site the coms protocol. This is part of why we have been hesitant to go this route too

[@patsmith3888]

Will there be proportional regen brake levers for hydraulic discs?

[@GrinTechnologies]

Yup

[@DD-co1zn]

I'm poised to buy a grin tech kit. Can this be used in conjunction with the Cycle Analyst ? Will the Cycle Analyst hardware that you're currently selling eventually incorporate the functions that are currently unique to this harness ? ... Ultimately, I want what the CA3 offers in terms of control and data ... But I also want the discretion of using the Egg Display, but without foregoing what the CA3 offers. If I could use both, I would 'hide' the CA3 (i.e wire it out of sight somehow, like in a small harnessed bag or something), and use the Egg display for maximum discretion.

[@GrinTechnologies]

ebikes.ca/getting-started/kit-types.html#ChangingfromOneStyletoAnother With a CA3 and a superharness the superharness'es throttle output will dominate, but in principle that could be resolved by just pulling back the sheathing and snipping off the throttle output wire of the SH device.

[@DD-co1zn]

@@GrinTechnologies Cheers, I'm reading that page. Ultimately, all I'm really looking for - in an ideal world - is to be able to use a discreet display, like the Egg display, while riding - but having the CA3 tucked away on the bike for programming/analytics purposes. I'm probably wishing for too much, and I think I'll just stick with the CA3. I'll keep reading though and maybe something about a CA3 / SuperH combo will click with me.

[@ambiorixcastillocina2730]

@@GrinTechnologies By removing the Throttle wire, which function will the super harness lose? Will it still be have the regen modes?

[@EwanColdicott]

Very cool - those are some pretty-looking displays. I'm excited about the bidirectional throttles (or analogue brake levers, guessing that won't work with hydraulic brakes though) but I'm running CA 3.13v2S (for solar tracking) - bidirectional throttles will "just work" with the older firmware though right, since it's simply a

[@GrinTechnologies]

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.

[@EwanColdicott]

@@GrinTechnologiesDrat, nothing's ever as easy as it seems. Well, assuming you don't have the time to merge the solar tracking features into the main 3.2 firmware, please could you consider backporting support for bidirectional throttles to 3.13v2S?

[@lyndsaybeck2249]

With tadpole trike is the software and hardware available to have a hub motor on all three wheels and have pedal assist on the rear wheel? Is it allowed in BC and rest of Canada?

[@GrinTechnologies]

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.

[@FloridaVolts]

This will sell out fast

[@hisforhack]

Great news about the Super Harness. Is the Super Harness compatible with the Baserunner Z9 or older baserunners?

[@GrinTechnologies]

We will be releasing a V6 Z9 baserunner within the next week, there were some last minute hiccups in that product. Use with V5 and V4 baserunners is possible in principle, but watch the last section of this video first to understand the caveats. We will make a white paper on how to do this but will not implicitly offer any support beyond that.

[@hisforhack]

Thanks.look forward to the new Z9 release and I will rewatch the "Boring Stuff"

[@AntonRu]

Bidirectional throttle? The twisting distance or radius is the problem imo. Twisting your hand all the time is not comfortable at all and when you have to go opposite direction do you need to go to 0 to a neutral point and then twist for the breaking system? I would do it so that in one direction it increases the more I turn and same if I change to the twisting backwards.

[@FloridaVolts]

When is this available to order with a grin controller only and not having to get a full kit?

[@voke999]

The manual for the 750C display looks like the maximum speed limit is 41 km/h. Is this the case?

[@alexhart15]

Love the idea of regen braking for my heavy e-bike! Any chance y'all would make a conversion video for a Lectric 3.0?

[@GrinTechnologies]

If you are willing to swap out the motor and controller, then you can use our standard front all-axle hub motor kit with the fatbike adapter set no problem. Choose the 20" fatbike rim option ebikes.ca/shop/kits-by-type/superh-kits/grin-all-axle-superh-kit.html If you wanted a rear motor, we should have the fat rear versions of the all-axle motors sometime in April

[@heidi5942]

Does this have any features that the CA3 doesn't have? And do you ship to Australia?

[@GrinTechnologies]

At the moment the CA3 does not support the bidirecational throttles and analog brake levers very well, but we will be releasing a little add on circuit to solve that so that they'll also have that features. What the CA3 can do that the superharness cannot do is: Backpedal regen control Speed limit regen control Assist level regen control (ie setting assist levels below zero assist)

Is brake proportional braking coming for the CA3? That would be sweet!

[@GrinTechnologies]

Yes, but via a bit of a hardware hack since there is no additional analog input available, so the brake signal will go to the throttle input of the CA3 (along with the throttle), but it will also trigger the digital ebrake input plug.

It is, but it already has a fully defined purpose. You are right though that with the digi aux input doing most of what the analog pot input used to be for, in most setups this isn't used and we could have this just be a simple regen brake input command. Hmmm, that's actually almost too easy.

@@GrinTechnologies that's great thanks. And is the harness compatible with the 850c display that comes with the Bafang Bbs02 kits?

Bafang uses a different communcation protocol. THe superharness is fairly protocol agnostic, but the ASI controller isn't and needs to be configured for which one. We decided for now to simplify things in this regard and only support KM5s based displays for the time being.

[@GrinTechnologies]

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.

Hey, your link doesn't work!

[@olivert.2968]

Can I add solar to the new harness?

[@GrinTechnologies]

You can always add solar charging to your battery pack but the superharness in no way indicates anything related to that. You'll just be able to see that the battery voltage slowly increases over time. You'd want to have a separate device to monitor the solar charging.

[@olivert.2968]

The CA is able to do that right?

[@GrinTechnologies]

Yes correct, the CA3 is in a whole different league of functionality than these generic displays for that kind of thing. But it's not colour or graphic.

[@topi_jarvinen]

IMO the original display is perfect.

[@pascalj4331]

"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]

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.
