  1. no not the age! lol was just wondering how fast some of you guys are averaging.


  2. I don't like going more than 25. 44t sprocket. Criusing range 15 to 20 depending on how she feels.

    I can ride as fast as I'm legally allowed. (rack mount)

    My first engine the Kings 70 or 80 cc whatever it is was pushin 40 with the 36 tooth but that was on a heavy bike and it had brake issues (coaster) so I got over the need for speed and got into crusin and now have a 44 tooth on it and putt around at 20 to 25 mph all the time. She'll still do 30+ easily but I got over the need for speed . I'd much rather take in the sights and (enjoy the ride). Where have I heard that before ? ? ?It now runs the 65 cc from Dac's but not for long. I'm puttin the 70 back on and puttin the 65 on a Firestone bike I got at a yard sale for 10 bucks. Turns out its a 1965 so the 65 cc seemed like the right thing to do.The 65 cc runs good but the 70cc pulls hills much better. Also I run both with all the natural oil they can stand ( at least 16 to 1 ) and rarely go full tilt anymore. Now as for me I was pushin 40 a long time ago. October 27th was my 56th birthday 65-56 those two numbers seem to be comming up alot lately. Hope I make it to 65 myself........ WV

    :cool:At maximum 8500rpm, i'm going 29.5mph on a 20" DAHON folder.:shock:

    With this same setup soon to be on a 26" bike, speeds of 40.7mph is predicted.

    at the moment, i'm pushing 61.

    29.5mph on a 20" DAHON folder!! Bwahahahaha! You are one crazy island boy! :shock: :-D

    Hey Pete, that's only on the nice long perfectly smooth flat. other than that,i probably buzz in the low-20's.

    I can't wait to finish my 26" bikes, so i can ROLL faster at the same rpm.

    and I AM crazy, compared to my baby boomer counterparts. my friends don't surf with me, because they're afraid of the sharks.:shock:

    average speed

    average speed on my bike 43cc staton chain drive is 30 miles an hr,depending upon my gear box outer sprocket,ive seen 46 miles an hr but lacks take off speed so 30 miles an hr it is.:cool:

    37 mph by the radar chrono

    My Kings 70cc/ 44T, on max-inflated 26-inch street tires, with me hunkered down low and throttle wide open, clocks in at 37 mph at my nearby "Your speed" radar warning display before a sharp turn.

    Coming from the other side of the turn is uphill at a pretty decent grade, with another radar warning, and I consistently clock 30mph UPHILL. I weigh 180, and my bike weighed 29 or 30 lbs before the motor.

    Funny thing is, as long as I watch out for bumps, the bike/motor felt stable at the speed. At least till it busted the bike frame last night. The engine leaks quite a bit fuel from... somewhere... but runs strong.

    I use 87 octane, which someone told me was less sensitive to humidity, and I put a little bit of isoHEET and Stabil in each tank.

    Oh yeah... I took off the lower part of the muffler and drilled a hole in the bottom of the pipe to let the gases flow straight through. The sound bouncing of the pavement is probably 95dB and I have to wear earplugs, but I appreciate the fact that drivers can hear me comin. From WAY back. Sounds like a 2-stroke Harley. :cool:

    what engine do you run?

    You need to factor in added weight of taller tires (which won't affect the numbers too much), but the biggest challenge at higher speed is wind resistance.

    Drive 40mph in your car with your hand out the window to "weigh" the resistance on your palm, and then consider the additional area of the whole frontside of your body. It really adds up.

    TF, I don't think Myron worries too much about a little weight here and there or even wind resistance. He probly goes at whatever speed he has decided to go.

    Made It To 40 MPH With Help From Wind And Gravity

    I have a 32cc Tanaka from Golden Eagle and I hit 40.1 mph going downhill with a 25 mph tailwind last week. Going into the wind on level ground my speed got as low as 13.5 mph. Most of the ride into the wind was at 18 mph.

    On level ground without any wind my top speed is only 28-30 mph even with the highway gear. I only weigh about 150 pounds. I always ride full throttle. Yesterday it was acting weird and started going 5-10 mph slower for no reason at all. I don't know what the problem is. The temperature around here was 50 degrees so I doubt it was overheating. My last tank of gas showed only 134 miles per gallon.

    Riding a Sun Recumbent Speedster CX with a GEBE kit 32 cc with HP carb upgrade and performance stack with air filter. Bike also has a fairing......On the flats I can go 39 MPH. Been clocked doing that by local police and was warned to slow down. I was in a 25 mph zone.

    Dang, Steve!

    That's pretty awesome. Recumbants are surely the way to go for the best aerodynamics, (for those who are interested in speed) :cool: You have a picture of your bike?

    I have hit 35 with my DE Scrubber. BUT got to thinking, a 50BFG hammering down the road with, oh say 1/2 inch of rubber total on the road, and not having the desire, and impaired ability to recover from road rash, I keep it in the 20- 25 range, enjoy the ride and everything will last longer. Engine, bike and 50YO BFG

    34.8 downhill, tailwind, 40cc tanaka rack mount by gebe, 14 tooth drive gear. Flat ground no wind, 29-31mph.

    :cool:Tom, I "cut my teeth" on a STATON friction drive and 1.60hp 33cc ROBIN 4-stroke engine. It's a great engine/drive combo to begin motoring. top speed on a slight decline was a gradual 26mph. there's a large friction loss, so the engine never reached max rpm.

    next came the 2.2hp MITSUBISHI and STATON gear chain drive on a 20" DAHON. excellent acceleration, speeds to 29.6mph, much less power loss and engine rpm maxing out.

    coming up is an old SCHWINN bike with friction drive, smallest roller, modified 49cc pocket bike engine, DELLORTO carb, advanced timing and tuned pipe to reach 35mph. because of large friction loss and high gearing, the engine's 9500rpm won't be reached.

    finally, a 4.2hp 40cc engine from a POLINI Italian pocket bike, coupled to a STATON gear chain drive and maybe NuVinci hub. the 35mph limit is still personally enforced, but acceleration should be very brisk.

    Yes, Tom, i can feel the wind resistance at speed. lately, i've been trying to rest my throat on my handlebars to reduce frontal area, but the bike gets more squirrelly when i do that.:shock:

    Anyway, it's not the actual top speed that gives me the rush. it's the ILLUSION of speed, and the acceleration. therefore, restricting top speed to 30mph or 35mph is prudent for me, because with high hp and low gears, brutal acceleration under control will be totally exhiliarating!

    I laid down a 8.295 sec. 166.9 mph quater mile on a highly modified KZ1000 at the local dragstrip some years back. You are right about the acceleration being what its all about. That was one fast motorbike thats for sure..... VW T in WV

    Hey, that were some fast rides you've had!

    Sweet, Myron!

    A few things that help with high-speed stability: long wheelbase, large true wheels with fat, smooth tires, and wider handlebars. I bombed a huge hill with my bike (before motor) and hit speeds in excess of 50mph, and might've felt safe there if I'd had anti-lock disk brakes. 8-|
