This is an extremely heavy, extremely stable bicycle. Although they aren't exceptionally knobby, it's in the nature of a mountain bike with wide tires, a straight handlebar and a massive frame. It feels like a steel frame with absolutely no flex to it. The only negative thing I have to say about it is that the manufacturer doesn't grind off the welding beads so the bike has a bit of a rough finish however, for an older adult to have your frame is actually very good, providing stability to somebody you may not of been on a bicycle for a while. The weight is completely offset by the electric assist. This is not a moped or motorized bicycle in the classic sense. The electric motor only engages when you peddle. It is intended to allow you to peddle easier and/or faster than you would without it, but it's not intended to drive the bike without peddling it all. In addition to forcing you to exercise a bit, this method of power assist provides more control over the speed of the bike, although the bike does move quite fast at top speed. I would estimate it is capable of going at over 30 miles an hour without much effort. This is a 15 speed bike with three gears on the pedal axis and five additional gears on the rear wheel axis. The gear shifter is premium quality, made by Shimano, a legendary Japanese bicycle parts manufacturer. The bicycle is very easy to put together, requiring an open end wrench and a couple of allen keys, both of which are supplied, and a Phillips screwdriver. It uses a disc brake system which is much more reliable than the old caliper brakes, which is very good because of the weight of the bike. The assist motor is housed in the rear wheel axle, and the battery pack attaches to the lower frame bar. The battery pack is locked onto the frame with a key lock, preventing theft but allowing removal for charging should you desire. The battery can also be charged mounted right on the bicycle. I can see using this bicycle as local transportation around town, saving wear and tear on the car and providing me with some exercise.
