WheelMaster is a reputable brand ... No mater what ... can't go too far wrong at that price!
If i start riding the trike around town i'll probably carry a blue hang tag and a copy of the federal law but bikes are basically ignored where i live.If the person presents a valid, State-issued disability parking placard or card or a State-issued proof of disability, that must be accepted as credible assurance on its face. If the person does not have this documentation, but states verbally that the OPDMD is being used because of a mobility disability, that also must be accepted as credible assurance..
columbiajack said:Here is my Columbia trike I built 3 years ago. 36v 500watt. The back tires are 20x4 1/4. The axels on these are pretty stout. they were used on garden tractors way back.The reason I know this is, I had to replace two axel bushings in the diffrential and thats how I found them

This columbia is a late 1970's. I had a 76 columbia I did, and gave it to my son. I like the columbia because it has a wider stance in the back, compared to anything made today and the two down tubes in the front of the frame.. Before pic below, and is the second later of the two trikes I bought. The Ad was a joke to say the least the guy thought this was a jewel, even though the back rim was twisted but to me it was worth it for what I wanted it for the frame and differential. Columbia's are hard to come by these days. Yes it came with the tractor 3/4 axel. I updated the junk ball bearings to sealed units.The columbia's came with a 3 spd hub for pedaling,. they used a sturmey archer and another make I don't remember. I swapped out the 3 spd for a 5 spd sturmey archer hub. I just installed a double crank sprocket so pedaling is effort less. The box houses a 36v 20 ah battery. If their were a way to put some suspension on this bike it would be a good improvement. But I think this grandpa is done,oobagooba said:columbiajack said:Here is my Columbia trike I built 3 years ago. 36v 500watt. The back tires are 20x4 1/4.

What year is your columbia? Do you have a build thread or before pics. Looks like you put some miles on the back tires. Did it come with a tractor axle? I think i saw someone with a jacobsen axle on here. Funny i used to have an old ford rider made by jacobsen but the rear end was more like a truck diff made by peerless. Is the suitcase full of batteries?
Mine is done for now. nothing like the columbia but for me it goes fine around the yard. 2.3 Kenda tires on the back with thick sidewall for 2 wheelin. Front is 2.4 "cheng chin" fat with good tread but paper thin sidewalls... probably fine for a trike front. at 20psi gives a lot of cushion around the yard makes all the wheelbuilding worth itView attachment 1can click on the pick and zoom in.
Next step more battery!
If you run round tread tires (designed for a bicycle leaning in cornering) low pressure is desirable on trikes.amberwolf said:oobagooba said:Front is 2.4 "cheng chin" fat with good tread but paper thin sidewalls... probably fine for a trike front. at 20psi gives a lot of cushion around the yard makes all the wheelbuilding worth
The thin sidewalls will let it flex more and probably soak up bumps better, even at higher pressures than you're running. But I've found ~20PSI on my CST "city" front on SB Cruiser has been about perfect for most bumps and for braking traction in most conditions here on the road...no motor up there yet (mine are in the back two wheels so the weight on there gives me traction for startups).
yep more flex better traction up the dirt hills.. + the flexy frame is decent on bumpsamberwolf said:The thin sidewalls will let it flex more and probably soak up bumps better, even at higher pressures than you're running.
You did good at $100, they would ask 250-up where i live. I paid almost that much for mine and had to replace almost everything... still looks rough. Mine has a 3/4 axle and sealed bearings too, so far they are holding upcolumbiajack said:This columbia is a late 1970's. I had a 76 columbia I did, and gave it to my son.

Have a big square tire on my 26" cruiser, plush & handles good. And a flat slik on my 20" stingray handles good for what it is, those tires last a long time but i don't ride the miles you guys do. The 24x1.75 trike rims tire choices limited, what i got works for me & cheap.. leaves more dough for a new battery..DrkAngel said:I prefer a flatter tread (as pictured earlier) for nearly full width contact during straight running and slight additional outer contact during hard turns (at normal pressure).
