Any of you convert a mountain bike into a cruiser?

Beach Cruisers Do you love balloon tires and fenders? Do you love riding the simplicity of a single gear and coaster brakes or a single gear cluster? Do you love the classic curves in the tubing of a cruiser that takes you back to the 1950's and 1960's, stylistically? Here's your home! Welcome to the Beach Cruisers and Cruisers forum!

Any of you convert a mountain bike into a cruiser?

Super duper nice job!!! I have a Bridgestone 400 sitting here that I've been trying to figure out how to covert. At first my stem from my cruiser didn't fit in the head tube. But then for some reason the stem from my son's Schwinn MTB does fit and I used a different stem on that one for the BMX bars.

I just need tires and tubes to fit the frame. I think I'm gonna use my cruiser rims with a coaster brake and put on 1.5" tires. Although 1.75's would work. I tried it with my Son's rims and the 1.95 tires and that pretty much fits but I think would rub a little. Don't your 1.9's come pretty close to the fork or no? I guess yours was a MTB. The 400 I'm referring to is a road bike.....

The only thing I gotta figure out is the different size of the rim in the dropout. I guess I'll use some washers. Or just wait for a cheap MTB and buy it. And use the rim....

As long as you're dealing with (1") MTB quill stems, no problem. The O.D. is 22.2 mm AIR. A BMX stem would fit, but is about 1 mm smaller in diameter, and will fit but could be a problem.

Looks Great! I would love to do the same for my old Hardrock. What type/brand riser and handlebars did you install? Thanks!

I don't think you're talking to me, but just in case you are, my bars and stem I have no clue what they are. They were on a cheap kids bmx bike I found for free. But they work.

Thanks 3S1M . . . you're correct . . . I was actually requesting input from Kirby999. Thanks again though!

1992 Stumpjumper



Not sure if this is considered as an official cruiser but it’s definitely not a hardcore mountain bike anymore. I love this bike and find it very comfortable to ride our city streets with.

This is my Burning man bike . The frame is way to small for my 6'5" but with the seat post all the way up and the Ape hanger bars it is a blast to ride

Procured a couple of 1984 Schwinn Mesa Runners while searching for a rear hub with 126 spacing. Kept the wheel from one and combined the best parts of the two to make my granddaughter's first MTB, er cruiser.

I just finished a mountain bike to beach cruiser conversion. I wrote a quick blog post about it if you want to learn about the details. The conversion was the result of wanting a 'casual' riding experience when I go on rides with my family on the bike path or around the lake. With a less aggressive position, I'm less inclined to push the pace - which puts me in the dog house The upright riding position allows me to relax and enjoy the surroundings. I list parts I used for the conversion in the aforementioned blog post, but the key parts are the super chill beach cruiser handle bars and big cushy seat. Some flat pedals, a kick stand, basket, bell and fenders round out the build, along with some Fat Frank tires. I opted to put some tubes with removable cores in the tires, and then added some Stans to the tubes to help keep a good seal on the valve (prevents slow valve leaks, making topping up air a less frequent need) along with the thorn or pinch flat protection it will provide. I’ve dubbed this build the "FrankenCruzer".



‘FrankenCruzer’

I really like this! Did you find a stock coaster brake wheel to fit in the rear drop outs or did you build your own? Or, did you cold set the drop outs to the proper width?

Gotcha! Didn't know if the axle would be long enough to do that.

I always worry about getting a straight chainline when doing something like that, but I guess you get it straight, then re-dish the wheel as necessary.

This is true. I have converted a couple of vintage bikes to SS and have been able to get a good chainline by merely changing the bottom bracket spindle width and/or moving the chainring in or out on the crank arm. Sometimes you get lucky.

I swapped the BB spindle with one that was 8.5 mm shorter and it gave me a nice chainline

Well, I guess you can teach an old dog new tricks. I've used mostly cassettes with my single speeds, so no problem with chainline. The couple of times with a freewheel hub years ago, must have gotten lucky.

1985 Mt Fuji. The paint was in pretty rough shape after years of off road activity with a series of youngsters in bike seats and it was going to be dipped and powder coated, but noticed the decals looked pretty good, so just masked them, then prepped and shot the frame. Decided to toss a spare BBS02 on to see how stealth it would look with a 52V, 4 ah battery in a seat bag (not shown). Frame, fork and headset weighed a portly eight pounds, but the entire bike came in at 41. Went on a 20 or so mile shakedown cruise along a dirt / gravel / concrete bike path and it's pretty competent if a little unforgiving.

My Burning man Playa bike . I love the ape hanger bars for low speed cruising but they can be a little twitchy . And make sure they are screwed down tight . I once left them a little loose after doing some work on the bike and the next time I rode it and put on the brakes they fell forward and I did a summersault over them landing flat on my back. Amazingly I didn't get hurt at all. Must have looked amazing to any onlookers.

That was a mtb? I wish I could find one of those hossack forks. I'd consider that a street fighter with the gearing, even with the fork on it. Iove that bike.
