Hello All, I have an Orbea Gain D20 which is a aluminum frameset and want to see if there are any Chinese manufacturers that I can buy just a carbon frameset so I can transplant the Mahle X35 system and the groupset onto? I'm not having any luck with finding a used carbon e-bike frameset online. Want to build a lighter weight e-bike with deeper profile wheels as well.
Aftermarket carbon frameset that fits Mahle X35 system...

I think finding a carbon frame upgrade would be very challenging. The rear dropouts for the motor axels are probably custom made for Orbea e-bikes.

Agree. You’d do better selling your D20 and buying an M series Gain. I doubt a Chinese carbon frame would be much lighter than your aluminium one. In truth, there is not a lot of weight saving to be had unless you buy top of the range stuff - carbon wheels, bars, race tyres etc - and any weight saving is negated as soon as you switch that motor on anyway! For speedier travel on the flat with the motor off, unless you are already super skinny, losing a kg or two yourself would be better (I could lose 20kg myself!)
You can have your existing rear wheel (hub motor) rebuilt with a deeper dish rim (or DIY) and buy a matching front wheel.
Gain D10 here, 14k kms so far.

I was considering this carbon frameset for my custom ebike build. I use the shell of the x35 battery to make my own internal battery, and then install a better motor and system that is cheaper to fix and maintain. However, it looks like it is designed specifically for the mahle x35 system to be fitted. The Mahle system is standardised, so the Orbea Gain should not have proprietary fittings.

Cor! Cracking paint job on that red frame! The only problems I see are getting a decent increase in battery capacity to fit within the X35 battery casing, as an increase in power of the hub motor by using an AKM or Bafang or whatever will mean 252Wh won’t be enough, and finding a controller to fit within the down tube in place of the one normally within the X35 battery casing, which constricts the available amps to the motor ( a replacement will likely be physically bigger). The hole cut in the top tube for the IWOC remote is irritating too, as most aftermarket systems use a remote that bolts to the bars. I don’t know if an IWOC can be made to talk to an aftermarket controller - if it could, it would be a neat answer. Otherwise, a blanking plate and maybe a bluetooth remote would be nice and neat, if available for your controller of choice…the Keyde systems are the cleanest, with a controller in the hub together with the motor (but I’d worry about heat) and a bluetooth remote, meaning you could use the entire X35 battery casing for battery cells, which may enable the extra capacity you’d probably want…Keyde don’t have the greatest reputation for reliability or aftersales service though…

I recently converted a Lapierre x35 frame for myself. I used a Keyde motor with integrated controller, and similar spec to the mahle. However it is a little faster than the x35. It is a brilliant system. Not had any issues in over a year, and aftersales support has been fine, although things take ages as its china. I rebuilt the x35 battery and got rid of the proprietary bms and leads. I repurposed the iwoc controller as a charging port, and the black bottle is a 180wh range extender I made. It can be run from an app, or a bluetooth button or display on the bars or garmin mount. It is actually quite neat, and I prefer it to the mahle system, as it is much easier to repair if stuff goes wrong.

I used the largest capacity 18650 cells available to me, with a good discharge rate, a fair bit better than the stock battery. I overbuilt just in case. I used Molicell P30b (3500mah, 30amp continuous discharge). So 252wh.
I originally wanted to fit 5000mah 21700 cells, in a 10s2p, but it was impossible within the x35 casing. So just did this, but it keeps it light and the range is fine. I have two bottle battery range extenders as well for big journeys, but still not needed them yet.
Having done a few x35 frames, I now think it's better to convert normal bikes with hidden cabling, running them off range extenders. A bit like the new Mahle system.
