If you want exercise, why choose a bike with an assist motor? Not a dig, genuinely curious.
Edit: I may be misreading your post
I will begin by stating that 30 years ago, my wife and I used to road and mountain bike a lot. This was on old-school rigid frame bikes.
My son took me with him today to El Corte de Madera Creek Preserve, which is to the North of and just past Alice's.
He was on his 2021 Stumpjumper aluminum Comp, and I was on my Turbo Levo SL Carbon Expert, bought yesterday. Thanks Santa (I have a fantastic wife, and no, she is not interested in more shoes or jewelry!) Her only ulterior motive may be that I have a heart attack and she is set. Teasing.
The ride was awesome, the trails amazing, and the company was great. Lots of single track, downhill and some F U C K I N G steep, L O N G climbs (and some that were super steep and short. Had to walk a few.
He is just shy of 30 and I am just shy of 62. I would have had an
utterly miserable day if I was not on an e-bike.
I felt guilty a couple of times when I passed him going up some grinder ascents, but I quickly got over it
Believe me, I worked damned hard, and my heart rate was way up there on the climbs in spite of the e-assist. One thing I learned today is that with e-bikes, when climbing, one can select too low a gear with a detrimental effect. Until I sorted that out there were a number of stupid-steep bits on which I lost the front end by way of a wheelie, which caused me to step off the bike. Except the time I fell off the bike..... I accept that part of the problem is my technique, not weighting the front end enough.
One thing that was really cool; during a long undulating descent that felt like a fast downhill ski run, we swapped bikes. Specialized and various reviewers have said that the Levo SL closely mimics the Stumpjumper. I must say it does. I fully expected to have to adjust the way I rode but I didn't. Specialized have done an amazing job with this bike. I did tell him that as soon as we started climbing we would swap back!!! He really dug the Levo SL and is looking forward to taking it on some of his favorite longer trails.
If anyone is close to San Jose/Campbell and wants to try this thing out, let me know and we will see what we can work out. Don't blame me if you are forever spoiled!
Merry Christmas!
