Orbea Gain M20i Mahle X35+ observations/performance - is it a 20mph bike?

I have been riding a 2022 Orbea M20i USA spec bike in the mostly flat Midwest for 4 months now with the Mahle range Extender battery. Love the bike! My observations on the Mahle X35+ system are interesting in that you have to work hard besides increased wind resistance to go much faster than 20-21 mph IMHO. See my comments below along with a general review of riding the Orbea Gain M20i on a daily basis in good weather:
  1. Pushing the motor past 20-21 mph creates noticeable drag on the motor, making it much more difficult to sustain beyond that pace for a long period of time. I do know that beyond the 20-21 mph assist limit I could just turn off the system, but that is annoying to constantly turn the system on and off, especially as I would not sustain a higher speed on flat road for very long.
  2. I had read that the motor does not like to be grinding in a high gear, and I do notice that even at 19-20 mph, the drag increases while not quite at the assist limit, yet backing off to 17-18 mph allows the motor to seem to recover and resume providing assist,
  3. Although the Orbea M20i is a relatively light bike, I frequently notice the parasitic drag when coasting that I wish would not exist. I just have to deal with it, but on downhills where gravity and momentum offset this parasitic drag it is not a problem.
  4. I find that if I charge the bike through the range extender, the status light on the range extender will eventually go out and just the IWOC light on the bike will stay white, indicating the extender battery is at full charge. As a note, I at least once a week I only use the internal battery even with a full extender to cycle the main internal battery off 100% charge to protect the main battery from being at a constant 100% charge.
  5. With riding gently at the green IOWC light setting (= 15% assist), I can get 40 miles before the range extender is done and now relying on the internal battery. Thus I believe a range of 75-80 miles is possible with sticking to 15% assist. However, I find myself further into the ride switching to the orange (60% assist) level, thus consuming 80-90% (red light) of the extender battery by 25-30 miles. With this hybrid setting, I believe but not yet fully tested that a 60 mile range using the orange (60%) assist level is reasonable.
  6. This bike and the 60% assist level make riding against a headwind really enjoyable, something that would just gas me on my previous bike, but admittedly consuming more battery life (as much as a 25% penalty on battery life!
  7. Ultimately, I find myself most comfortable given the design and limitations of the X35+ motor riding closely to the 20 mph but not much faster when on level surfaces. I am not unhappy with this, as my average speed is now significantly higher than my previous road bike, getting a good workout, but not feeling gassed at the end of the ride.
  8. Outside of prudent chain and gear cleaning/relubrication after riding in crushed gravel, the bike is very low maintenance. The standard spec Schwalbe One 30mm tires with standard butyl tubes running 65-70 psi are great for riding in my area of mixed asphalt and crushed gravel, provide a very plush ride compared to my previous road bike with 25mm rims and tires, and hold pressure well.
  9. The 12 speed Di2 system and shifter paddles (now using syncro shift exclusively) are a joy to use, and with nearly daily riding, need recharging every 2 months. Likewise the hydraulic brakes are a joy compared to rim brakes, with only one time thus far needing to pump the brake levels to work air bubbles out of the front brake and resume normal braking function.
  10. Overall, I am extremely happen with my Orbea Gain, that now encourages everyday 25-40 mile rides that I would not have frequently done before, especially for a senior rider like me. Congratulations Orbea on a great design, pricey but well worth it.

hi
i orginally has a oebea D50 did 5200 miles in a year 25 miles a day every day, and yes dragging wheel after 15.5 mph yes its uk limit, went to M20 ultegra mech gears 2019 what a difference 4 kg lighter and yes dragging wheel did 7200 miles in 16 months on this bike, it is a great bike i now have a scott eadict x20 motor much less drag on on this bike if any, the drag on the x35 adds about 1kg in comparrison weight and i wish we had the same cut of point as the USA 20mph , as i said at 15.5 mph motor is off this realy sucks
