Had my Trek Rail 7 E bike for a while and the whole e mtb is just awesome

Ridden in mixed groups and just use the lowest power setting and still good workout and always advantage on uphill with the fittest rider.
On the down trails the low center of gravity is great as you carry momentum and flow.
Have a really good rider on "huff and puff" to stay on your tail.
If one of your riding mates is felling buggered then swap for section and put in higher power to give him a rest.
On a wider fire road uphill section stick in turbo and give a mate a tow.
I've done rides with just e bikes and that's where its too much fun making some trails that were hard work a pleasure.
Generally using second power mode but easy to change from tour to emtb if need it.
I've only used Turbo on steep climb that I would have pushed or if heart starts to afib can take it easy.
If you are thinking of e bike then try one
