EMTB with more than 750 watt motor?

60% lungs capacity

62. Not far off, in 2020 I had widow making PEs and the found a mass and said it was probably stage 3 or 4 lung cancer. PET showed nothing luckily and the mass was decaying lung tissue from previous PEs. I started out worse than that, not sure where I am at today, I have spent the last few years riding hard and rebuilding, im close to normal and ride 5000 miles last year and 2800 so far this year. Had a stent put in 2023, after a heart attack, but that only improved strength.

15 months with a emtb, almost 25-30 miles a day. Lost 20 lbs and I am strong as an ox. Almost the best shape I have ever been in.

Good question, might be because there are numerous hills steeper than 17 degrees and I am 79 years old but want to continue to ride.

I’m 78 years old and have a Bosch with 85nm and 600w. I regularly climb rough tracks of over 30% and have never needed more torque or power. Any more power would likely cause more slippage. I would suggest you get a larger cassette ring, mine is 51 tooth but quite often I don’t need that. I’m 80kg and not particularly fit.

The power games are definitely unnecessary for actual mtb riding. The only case I could see wanting more power/torque than the 750W/100Nm range are people trying to use their e-bike as a moped with a throttle on the streets with little to no pedaling.

I do 90% of my riding on a custom assistance level on my M560 that only peaks at ~520W (40% of max power) and the other 10% when I’m climbing a big hill on another one that peaks at like 610W (50% of max power). Anything more feels like I’m not even powering the bike at all and just seems like overkill. 750W is more than enough IMO for any normal type of riding meant to feel anything like actually riding a bike.

Have you ridden the new firmware with EMTB+ ? It is anything but smooth. My mate pushed down on the pedal and the bike shot off, then continued to over-run. The bike got completely away from him. He could only hang on with one handlebar grip as the bike tried to do circles around him.

Anyway. Maybe it's particular to his motor. But I wouldn't be telling a 79yo to use EMTB+ mode, when I've seen it behave so badly.

I have Gen 4 and used EMTB+ for first time on Friday (29km ride, used that mode for 9km), admittedly I only had the Dynamic Assist at +2 but it all was very smooth and definitely more powerful. My four modes now are ECO, AUTO, EMTB, and EMTB+

I think you need to test some bikes. Particularly the new gen 5 100nm Bosch. Emtb+ in 100nm will eat 17 deg for breakfast.

That sounds like good advice. Do you have a suggestion on which bike manufacturers to look at? I live about a 2 1/2 hour drive from the nearest city.

@Cybersnow

2025 purchase in the US, your safe bet for bikes that will be supported are Trek (Bosch) and Specialized (Brose). I have owned several ebikes since 2013 and have had 2 that were orphaned with no support.

Big brands that have pulled out of the US market include Haibike, BH, Stromer and several others. Having a 5 to 8 grand bike with no parts or service is no fun. Ride before you buy.

Not here. We like racing these things.

Depends on what you want to do, if you ride fast and trying to beat the sun, or trying to beat a storm, more power is awesome. Here competing on Strava is a big thing, a lot of us enjoy it.

My average ride is 25 miles and 4000' of climbing, and having more power is a good thing on all the 1000' climbs.
