I have a huffy 3.0 fortress mountain bike, I have to ride on some bumpy roads and trails, I have a friend who has a bike that has suspension. I rode it once and it was very smooth when I went over a speed bump. So I wondered if it was possible to install a suspension onto my bike. I tried to search it up, but I didn't find anything helpful. So I decided to see if any of you can answer that.
You could add a suspension fork (this bike seems to come with a very low quality one) or suspension seatpost or suspension stem.
On such a low end bike though, only the suspension seatpost would make sense -- for the other options, you're more likely better off getting a new bike.
Another option is to get the biggest tires that fit and run them at a low pressure, which should provide some shock absorption. But this bike wasn't intended for use off-road really -- just to be ridden a few miles on road.
You can but if it was ME, I wouldn't do it.
The fork would cost more than the bike is worth. You may be able to find a used bike that accepts larger tires at the or near the same cost as a good quality fork. I ride with a bike shop mechanic that has a bike with 4.25 or 4.5 + size tires and it is surprisingly softer on bumps than most full suspension bike. I rode it and was amazed. You also, have the added benefit of not having to replace expensive suspension parts when they wear out
If you add front suspension you must worry about geometry and handling changes. Is it possible/sensible to add a suspension fork to an old mountain bike?
A paralellogram seatpost is helpful. Until recently, only Thudbuster was available by their patent ran out and now there is plenty of identical looking competition.
I was doing a lot of off road riding on a Surly Crosscheck. I got a Thudbuster seatpost. It helped a lot for the shocks on my rear end. But it didn't help at all for the shocks on hands and through hands to head. After about a year I developed a focus problem in one eye. Got a full suspension bike and have never looked back.
Now I went the opposite way. I put aerobars on the MTB, which is great for long distance mixed terrain riding, so that I can take the weight off my hands now and again on the road parts.
