HiHi,
I'm looking at purchasing a road bike with the Mahle X20. Just wondered how reliable the X20 is ? Is anyone else running this motor, how has it been ?
Thanks.
3.72 Wh/km on a trip with 600 m elevation gain? It is not bad at all; in fact, it is an excellent battery consumption factor. Meaning a lot of your own leg power input!Hi
I’ve been using a Scott Addict E ride since January with Mahle X20 240W battery motor and have had no reliability issues however I have had range issues when using it I can get 40 miles from it at an average of 14mph with 2000 ft of climbing using only level 1 power.I purchased the range extender which gives me another 25 miles
This is the reality for any type of low power lightweight motor with a small battery. At low assistance levels, the system is pretty economic. Go into the high assistance mode, and the range goes off the cliff, especially on the climbs.If I use the higher power level on climbs I find the range reducing significantly
These are marketing values based on a lightweight and strong rider on the flat in ideal conditions.The manual states a range of between 40 - 100km per charge
Indeed, the specs of the e-bike do look excellent.I do find the bike nicer to ride with the drag free motor than the X35+ and the benefit of a rear thru axle
Perhaps the difference of the X35 of 40 Nm max compared to x20 55 Nm can explain the discrepancy. More max torque means more motor peak power, hence bigger battery consumption.However with the X35+ I didn’t seem to have the same range issues
Slightly for sure. Even if British winters are rather mild, winter riding is slow and emptying the batteries faster than it happens in the warm season.I’m wondering if riding the X20 during the winter months January - March 5° - 9° May have reduced performance slightly ?
All depending on your own leg input! I ride a Vado SL with a mid-motor in the plains but I certainly need far more of assistance than you do, and my battery consumption factor requires me to use not only one but several Range Extenders on my long rides! Does the X20 allow you to tune the assistance?However I’ll be happy if I can get 65 miles out of X20 Scott with range extender and 3500 ft climbing
Oh, the e-bike is indeed beautiful and I only can regret my shape of health does not allow me riding that kind of e-bikes!Love the bike it’s a stealth Carbon Beauty

Hi Stefan
Yes you can tune the assistance for % of the 3 levels but I have found anything above 40% gives you great boost but rapid battery use So I tend to use 35 - 40 % of level 1 which gets me along comfortably at 15mph and up hills using low gears

Mind there are 2 battery option levels available 250 W/hrs and 350 W/hrs at a difference of about £500
I did have the bike checked over by a Scott dealer who contacted Mahle and they confirmed battery and motor all ok using there diagnostics
So just need to get out and and ride it in the summer for up to 60 miles and a few Northumberland hills
I anticipate a mid motor in a few years time when I hit 75
I get power output and cadence display on my Garmin from the AddictAnother question for Scott X20 owners; do you find the riding position to be more 'sport' than 'endurance'? Comparing riding style between the Addict and the new Solace.
same here, I also use a Garmin Edge to get this data.I get power output and cadence display on my Garmin from the Addict
My position on the Addict is quite upright with the saddle only slightly higher than the handlebars and 3 spacers under the stem The frame is medium and I am about 5 foot 10 inches in height
I also have the brake levers fairly high up the handlebars I
I don’t get the option for cadence or power (human) on my Edge 830 with my X20 Wilier. Did you have to do something additional to make this work?same here, I also use a Garmin Edge to get this data.
Upright position is of course relative. After all, this is a racing bike. Wouldn't really call it upright seating but I read somewhere that it's more moderate than some other racing bikes.
Buy a mid-drive motor e-bike by Specialized or Giant. X20 has no rider power meter because a hub drive motor does not use this information.I don’t get the option for cadence or power (human) on my Edge 830 with my X20 Wilier. Did you have to do something additional to make this work?
If you believe the marketing then it reads rider power input and cadence to vary motor output. My lived experience is that it does this in a pretty coarse way. I think the posts above were probably referring to bike power anyway but I would like to get cadence reading on my Garmin.Buy a mid-drive motor e-bike by Specialized or Giant.

While the X20 certainly has a cadence sensor, I do not think it has the proper torque sensor; or, the torque sensor in X20 does not do the calculation of the Pedalling Power = f(Torque, Cadence), so the leg power cannot be reported. The mid-drive motors I'm riding not only do that calculation (it is necessary to determine the assistance motor power) but also report it to Wahoo, Garmin and Karoo2 via ANT+.If you believe the marketing then it reads rider power input and cadence to vary motor output.

Please report your findings. If you can really get your pedalling power from the X20, then that would be a very good information, and then I am ready to say sorry for my wrong views!I worked it out. The bike has a second ant+ sensor which only shows up as a power meter type on my garmin. That provides cadence, speed, and power. I was previously searching for a cadence meter and getting no results.
On power all I know for sure is that Mahle state it does record pedal power with over 95% accuracy and it sends data to my garmin that seems very similar to the power meter on my non-electric road bike. I’ll have a proper play at the weekend. The good thing is that I now have cadence working which is what I was mainly after.
