Evertime I make some decent progress it seems like something else in life pops up I'm getting close I got the chainline all set, the jackshaft needs to be replaced as I got one of those cheap 45 dollar ones from eBay and the I'd on the bearings was 14mm so I ground down the shafts just to install it to get my chainlines set. Has anyone else had problems with those cheap jackshaft kits I. Amazon and eBay or did I just get unlucky? They all look the same. The brackets and everything else was decent for 5he price just wrong size bearings which will be replaced and a new shaft. Anyway got everything from the tank back figured out. I found a decent mtn bike front suspension fork in good shape so I can put 203mm discs up front. Once I get...
NOTE: This came out to be a lot longer than expected so just be prepared to read lol. So I'm gonna use this to show where I'm at with my hobby for now and also point out what I've learned from personal experience. What I say may not apply to everyone so don't take my words as something general. But basically, when I first built this bike I got the help of a friend who knew about it more than me. The build was solid at first but there were many things I should've changed about it looking back at it. Leaving things stock came out to become a nightmare and many things were breaking/not working at their fullest. - First thing I think I should mention which ultimately cost me the most and caused the most headache is the rear sprocket. The...
I am getting back to my bike after my dog died about a month and a half ago. I'm wondering about my chainline coming to the wheel from the jackshaft. The bike originally was a hybrid and had 700 wheels and I don't know if I'm going to be able to fit this 26 coaster wheel. Perhaps have to heat and bend the chainstays a bit more. I already bent them a bit inwards to fit the hub as the bike originally had a 7 speed cassette and was to wide for the hub. The rims 28mm wide and I would like to what the thinnest tire anyone has successfully used on a coaster brake wheel. Any advice, criticism, or encouraging words would be appreciated.
not sure what brand of bike or motor but with a little bit of work ,this how she turned out. welded some solid motor mounts,was getting tired of the janky u bolt and etc. but anyways,boy oh boy are these things fun!! wanting to install disc brakes but i’m not sure of the size of the disk and wut not or wut will work on this. i’ll have to weld brackets to mount the caliper.
Oh my. I stopped here for my mental health. I added some update photos for my urban fatbike. A few things changed for 2023. I used some focused LED lens caps on my indicator / turn flashers. Now they are visible from the sides AND I can see if I left my turn signal on. Tinted some lower headlight LED panel bulbs to make a yellow-bordered arrow, as they are tied to the signals. Tucked the headlight in, moved display forward, added a handlebar bag, new Tribit Stormbox Micro mounts. They flip up, both to get in my front bag, or to blast rude music forward 😈 Down, they're closer. I can go down the hill, tuck in with my face in the speakers, and I'm 16 again riding in my car with the Mindblowers cranked to 10 muhuaaaaa... I have to...
I finished my break-in of replacement 48cc. It went lots smoother with everything else nailed down. I'm shooting for a lot more than 700 miles on this one. I reworked everything, found the good, fixed the bad. The jackshaft mount held up good considering it took a lot of hits, bearings good, shaft good, and crankset side good. But, it still had a twist, probably from when I tossed it over a hill. Knee and calf still hurts so yeah beyond operation parameter. The 21T sprocket only 415 width, wore out, chain wore out. Too thin too much slop. I redid engine mounts and welded a stiffener plate to jackshaft bracket, welded up a mount spacer for engine, drilled exact fit. No more sloppy wallowed out hole, no shims. I shifted engine a bit...
A bike I built for my uncle, was a fun project. There was a bunch of learning and customizing involved. The bike runs really smooth, hard to tell if you’re riding a bicycle or a motorcycle, really a different ride. These motorized bikes are really fun, a good fun thing to do, definitely addictive. This was my second build and I’m already starting on the next one! Lol
A pexmor 48cc kit on a 94 Trek 820 frame with a 21" center tube. Bought the dual brake lever at the bike shop and the mirror on amazon. The rest of the parts have been generously donated by walmart bikes that have been parked for years in my family's garage. I need a new cdi as the one that came with the kit reads OL when trying to test the capacitor (multimeter has a capacitance measure mode) and I get no spark. Magneto and coil works because it read 3.3 VAC (turned by hand) Waiting on my next paycheck to get the correct derailleur and a new cdi. I'm not happy with the chain tension. The stock tensioner doesn't seat the chain properly due to the angle of the chain stays. The chain is as short as it can be with whole length links, its a...
Round 2.. lol.. had an issue with my other case so I had to do a complete rebuild.. all new SKF crank and clutch bearings, balanced crank with AF80 rod and wiseco needle bearings, Slightly modified piston, shh.. I used Athena's window design.. lol.. it's also gasket matched, case port matched. ARP head studs.. why? 160psi in my 0.76mm squish gap is why.. all fed by a Mikuni vm20 and some Sunoco GT Plus 104 that I'm going to get in about an hour or so when they open.. I know I don't have to but I want to.. besides when someone else is paying for it, I'll get it all day long... Should be a decent little beast tho... I hope 🤞 I'm goin to get some beer.. I mean breakfast. Ehh whatever, breakfast beer sounds good
Was getting my bikes out for the upcoming move. This bike hasnt seen the light of day for years. Thought I take a few pics. The build is basically finished, just a million little details. The Villiers is driving thru the bottom bracket directly to a clutch on the right side to a 3sp IGH. I did something I have wanted to do but have never done, is to convert a coaster wheel to a front brake. Notice also where the rear brakes are. Should be a cool old school ride. Its a true 100cc. The old Villiers are smooth, torquey runners that dont rev overly high. The engine is an early 30s and the frame is a 36 Cleveland Welding step thru.This one may reach forty. Will be badly under braked at that speed, will keep it as an easy going 30ish cruiser.
