    Red face Classic bike to cruiser conversion

    Hello everyone, this is my first post in this community. I own a classic city sport bike that I would like to transform into a comfortable cruiser with some nice fat tires.

    My idea of conversion is to keep the paint or maybe repaint it and lack it in high gloss and reinstall the original stickers, replace or maybe remove the fenders, replace rims and tires with wider (I think there is a 4,5 cm gap), remove the front derailleur and install rear hub gear system. This is the look I'm after.

    Anyone can give the cost estimate and any further suggestions or heads up on my ideas?

    Three speed coaster brake hub would be nice. New seat of course. What size tires are on it now? 26" can be 4-5 different sizes, check the fine print on tire & rim. Standard mountain bike/beach cruiser 26" is 559mm.

    Good starting point. I prefer powder coating. It's not that expensive ($80-$125) easy and you get a durable finish.

    First find out if cruiser 26' (559 mm) wheels will fit your bikes frame. I'd guess the forks and rear stays will be to narrow.

    I 2nd this. I have a nice 5 speed bike, switched to a fat balloon tire not thinking about frame clearance between the front fork and also the chain stays....I got lucky and they barely fit, but I had to true the wheels perfect to keep them from rubbing.

    I also had to change my fenders, my others were too narrow and if you want that "tight to the tire" look, your new tires are going to need to tuck up in there.

    It turned out my bike is a 28er, not 26er. I measured the gaps between the fork tubes and rear triangles and in both cases the gap is around 5 - 6 cm, so I think I'm on the safe side, right? A bit tight though, but nothing a hammer can't fix. Should I pay attention when selecting the rims, so that for example the rim doesn't make the tire lower and wider in the profile causing it to rub against the tube? What kind of rims should I get?? I want to install nexus inline-3 hub. I enclose some additional photos of my "blue bentley".

    stick with the original rim, if the are good, "28 incher" and "29'er's are both aka 700 C. Toss on some 700 x 35 to 45 if you want wide rubber. changing to 26 inch is going to cause you brake woes finding the right reach arms

    I never said that I want to convert it to 26er, I want to put on wider tires and rims with rear hub gear system.

    3 speed hub with 700c rims and fat tires. Might have to be a custom build.

    I was thinking that myself...not sure you can find anything off the shelf, but you can build something pretty nice I'm willing to bet. It seems like a nice bike, it would look good stock as there aren't a ton of them around...that being said, I understand the want to make it your own, just keep your goals simple and if you want to keep things inexpensive, keep your eyes pealed for donor bikes.

    Can anyone give me a hint on how to mount the seat more to the rear end of the bike? It's current position is way to forward and I have a "road-racing-bike-feeling" on it. The seat is already mounted on the beginning of the rails. I hope I was clear. :S

    I am thinking on installing Brooks seat. Is it really worth 100 €?

    What you need is called a "setback seat post" that will move the seat back more over the rear axle.

    What just hit me is will the powdercoatet rim keep its color because I have the old type side pull caliper brakes? I'm afraid the paint my come off due to braking after time.

    I'm also sceptical about the 3-speed nexus hub, because I have a big front sprocket, 52 tooth. What will this mean for lower gear transmission ratio? Are the gear ratios between the three gears significantlly different or is there just a slight change? I have a few hills I need to climb and at the moment they're quite a challange , and it'll be even worse when I put my daughter on a babyseat (15 kg extra).
