Havn't been on a bicycle in 45 years, till just a couple months ago. After trying one of the "hyrids" I traded it in for a Trek mountain bike. When I test rode it it just felt more stable and comfortable then the hybrid. Maybe it was just a bit lower to the ground or maybe the big fat tires, but for sure it was the ultra low gears and the hydralic brakes!. I live in the middle of a hill and going up is never going to be easy or fun, but with the gears and the 26" tyres it's doable, and going down the hydralic disc brakes are solid.
The only real problem is I remember bike riding to be much easier back 45years and 80 pounds ago.
