Need comments on proposed folder build (Swift or R20) – WARNING LONG POST
Hello All,
I would like comments and suggestions for my proposed bike build. I want to build a folding bike with the following main qualities: sturdy, simple, and durable. After research, it seems the Xooter Swift and Raleigh Twenty are good sturdy platforms to start with. I want to use standard bike parts and it will be a singlespeed w/ coaster brake (I’ll probably add a front brake). I want to use mag (plastic) wheels, classic Skyway Tuff wheels, because I like the look and I will ride on the beach. I will mostly ride on the street, but I live in Florida so I will definitely hit the beaches. I took my MTB on the beach several times, and after several months spokes began falling off. I rinsed the bike after each bike ride, but I guess it wasn’t enough. Does anyone know if the Skyways will fit the Swift? I know the wheel spec on Swifts is 406, but I don’t know if the Skyways are also 406. I haven’t seen any Swifts with mag wheels (there are R20s with them though). I have an 80’s GT Pro Performer with mag wheels, and I suspect they have similar specs as Skyways. If no one knows I can probably buy the Swift frame and test them out.
Alternatively, I’m looking into building a Raleigh 20, but after a lot of reading, there may be a considerable amount of work in finding standard modern parts that will fit. Plus I don’t want to modify the frame (i.e. cut down head tube, rethread BB, etc.) Seeing the many custom R20’s, I know it’s certainly possible, but I don’t want to spend months building the bike.
Below is a list of parts I plan on getting if I was to build a Swift. All parts (except wheels) are from bikepartsusa.com and are pretty standard. I’m not absolutely sure if everything will fit, but from what I can tell the Swift takes mostly standard parts. If anyone can confirm whether something will fit or not, please let me know. I believe I covered everything to build a rideable bike.
$499.00 Xootr Swift Frameset – Silver. Includes frame, fork, headset, riser w/QR lever,
derailleur hanger, and seat post w/QR levers)
$129.99 Skyway Tuff Wheels with coaster brake (don’t think cog is included).

Thanks for your help and Happy Holidays!

Looks like a cool build, but two thoughts:
1. that chainring won't work with that crank. The crank looks like a five-bolt, 130mm BCD crankset, and the chainring's for a one-piece crank. You'll need a matching chainring.
2. You may not need to go the plastic wheel route. Riding by the beach every once in a while shouldn't be so disastrous for a spoked wheel; I keep an old fuji touring bike with galvanized spokes out on long island for just that purpose, and I haven't broken a spoke yet. I'm also reminded of all the winter bikers up in Canada who deal with roadsalt daily on spoked wheels. I wonder if the old MTB could have been having spoke breakage for other reasons, like overtensioned wheels.

Do you have experience with that saddle and those pedals? I ended up taking the folding pedals off my Swift and putting non-folding ones on. Since it's not a tiny-folding bike in the first place, the slight increase in folding size didn't matter.
The saddle doesn't look comfortable to me, but that's so personal, I won't try to say it's a bad saddle. Have you ridden one?
I'm not sure the twist-shifter will slide past the curve on the bullhorns--but I'm also not sure it won't. Any chance you can try it out before buying?

Oops, missed that. I'm used to the stock Swift.

I've seen salt and sand really take their toll on a bike in no time at all when it's ridden on the beach, not merely at the beach. The plastic wheels with sealed bearings make good sense for the beach, as does the single-speed. However, if sand and grit get on the Swift's seatpost and inside the seattube, it may abrade the alloy inside the seat tube. Extra care when wiping down the seat tube and seat post after a ride on the beach would be prudent.

Think about that pedal choice
I had folding pedals like those on my Downtube Mini. Convenient to fold but very slippery in wet conditions and no provision for adding toe clips. I upgraded to MKS AR-2 EZY detachable pedals and added PowerGrips straps. Removing the pedals takes not much more time than folding those plastic pedals, and the PowerGrips straps make convenient hangers to hang the pedals on the handlebars when I need to stash them somewhere quickly.

Regarding the chainring: That looks like the kind of thing you want, but make sure that the crank is 130mm BCD as well-- it could be 144, or 110.

Just realized I have these on my GT. Also just found out they come in white! White tires are hard to find and my GT has white wheels. Now I can buy the white tires and swap the black ones over.
Speaking of the grit-in-seatpost issue, pick up some fenders from Xootr-- they make a version of the planet bike ATB fenders with "custom" mounting hardware. There's plenty of clearance for the fenders even with the fattest tires.

Great advice! Thanks everyone! With the changes and additions, I'm just over $1,000 (amazing considering many of the parts are relatively low end). Just a few weeks ago I was thinking I'd find a used folder on craigslist for ~$100 just to try it out...
Regarding the coaster brake cog, I found a 16T Suntour on the Skyway supplier website https://www.coloredtuffs.com/shop/ind...&productId=299
I would like to get a smaller one and found this 14T:
There are other sizes on the Sheldon Brown/Harris Cyclery site: https://sheldonbrown.com/harris/sturm...html#sprockets. The inner portion of the cog looks pretty much the same as the Suntour. Except for one indentation and it not being dished, it looks like it will work. Anyone know? Too bad the Man himself isn't here to answer.
A 14T cog combined with a 56T chainring will give me 74.7 gear-inches. That's about the same as the top gear on the Giant Halfway I have now and I think that would suffice as a SS.

Buy at stock swift, ride around, swap out parts as needed.
Alternatively buy a cheap dahon or downtube and build on that.
I think Dahon has a mariner bike which supposedly is rust resistant.
Do they still make the Strida 3 with mag wheels?

FWIW I have 53/14 on 1.5" = 72" gear.

Here are some SS ratios for common bikes:
Single Speed Beach Cruiser: 54-63 gear inches
Single Speed BMX Bike: 53-55 gear inches
Single Speed MTB: 52 gear inches
Single Speed Road Bikes 70-72 gear inches
These are ratios that are considered optimal for the type of bike, and matched for the intended use. But then again, everyone has their personal preference.

The Skyway mags will work, but you'll need a longer axle and spacers. I'm pretty sure BMX bikes have 120mm rear spacing, and the Swift frame will have either 132.5mm or 135mm spacing.
I use to ride one of my BMX bikes on the beach as well. Definitely buy sealed bearings for the BB, a neoprene headset dirt guard, and repack your wheel bearings. I would recommend that you buy a grease gun. When installing that new axle in your Tuff Wheels, completely fill the cavity between the left and right bearings with grease using the grease gun. That should help keep the water and dirt out. I wish you can still buy O-ring chains for bicycles, but until that happens, I'm holding on to my old Acme chain for ransom. Get one if you can find it.

I was planning to test ride the Swift on Monday at Trophy Bikes in Philly. Unfortunately both Trophy Bike stores were closed for the holidays. Their website says they're open everyday and there was no mention of closing for 10 days! Their answering system doesn't even mention it! It just says they're open everyday.
joseff and edwong3: When I rode the Giant I believe top gear was sufficient for flat land. I'll have to try it again to see how it is on the hills. But at this point since I didn't get to test ride the Swift I have to figure out what to do. Since they have a no questions return policy, I could buy one and try it. But shipping back and forth is kind of a hassle. OTOH, I get to test ride it for a month instead of just a quick test ride at the shop.
sqynt - Thanks for the recommendations. I heard from Xootr and they said the front dropout spacing is 100mm and the slots both front and rear are 10mm (3/8) so they will fit the 3/8 Skyway axles. I took quick measurements on my GT which has wheels similar to Skyways and dropout spacing is ~100mm (front) and ~110mm (rear). I have yet to hear from Skyway about dropout spacing (including locknuts). I'll have to ask them about axle length.
I haven't had to change out a rear axle before. Would something like this work? It looks like it's 155mm wide.
Jam rear hub axle set. 3/8x26x126x155, with dust caps, $2.99.
or this? 165mm
