New study finds e-mountain bike riders get the same exercise benefits as cyclists on regular bikes

Jack first became fascinated with e-bikes when an elderly gentleman breezed past him without a care in the world up a big old hill in North Wales - thus realising e-bikes are the real deal! Although he genuinely enjoys time trials and lung-busting climbs without assistance, Jack likes nothing more than cruising round town on an e-bike during his days off.

So, over the same distance and with the same effort, the e-bikers did it 12mins/4mph faster because of a motor.  Sounds like cheating to me.

Someone going out for a MTB ride, or indeed a road ride, for fun and exercise, with electical assistance, is likely to adjust the speed or length of their ride, because they will ride until they feel they have had enough. But someone using an e- bike for their commute is definitely cheating.

So th headline is therefore incorrect. They get 5% less HRM over a shorter time, so for the same distance they get less exercise. If they rode faster and longer they would get 'the same' as normal riders. This is meaningless. You ride a bike you work your heart, you ride an ebike you work your heart less and bring a massive battery into the world - hurrah!

The eMTB riders were at 95% heart rate of the std MTBers, but in the limited scope of the study the std MTBers rode for 48% longer.

That 5% on heart rate is probably quite a "big" 5%. 

So to get the same exercise "benifit" the eMTBer would have to ride more than 150% of the distance than a std MTBer.  Timewise roughly the same, but are eMTBers going to ride 1.5X around the trail park?

Or always go the long way on the commute, of course a road legal ebike would offer more exercise benifit as the max motor assist would be lower (study was 20mph),  Not sure what the power assistance was, the 2018 Specialized Turbo Levo FSR Comp Carbon 6Fattie in UK spec I found listed as 250W nominal.  The USA version in the study may have been higher.

I would argue that a 10bpm average over 12mins could be a significant difference in 'quality' training terms. However exercise is exercise and it's 100% better than sitting on the couch!
