Boy do I resemble that remark! At 57 with three knee surgery's on my left knee, and another one likely on the way, knee issues are always a concern. Add in a back and wrist surgery, and I'm certainly feeling older than my age might suggest. I've always loved mountain biking, but with advancing years I've been getting slower in the climbs, getting passed by others (hate that!), unable to ride the distances I used to, and running my heart rate in zone 5 for most of my rides. It wasn't as fun as it used to be, and I started riding less. Enter my 2022 Turbo Levo (expert). I feel like I'm in my 20's again when I'm on this bike! I love it! I call it my "Time machine" instead of my E bike. I'm riding longer, faster, having WAY more fun, burning more calories, and doing so in a much "safer" zone 3 or 4 heart rate. I can ride for several hours, then go do it again the next day. I just turn up the power the next day and can go just as fast as the day before. On my analog bike, I was hurting for days after a ride, and wouldn't even consider trying to ride the next day. The only problem is the added capability of this bike is making me want to do things I probably shouldn't be at my age. I'm going off jumps, blowing through rock gardens, and taking lines I never would have considered on my 120mm Spec Camber Pro. These bikes are a lot of money, but its the best money I have spend when I factor in the fun and exercise factor I'm getting back. I thought I'd still want to ride my analog Camber, but after getting some time on the Levo, I haven't ridden it a single time. I just have SO much more fun on the Levo, the Camber is just collecting dust.
