Any ideas on how to increase the up-hill power on

B Perkins /

For some very steep hills, the TFR won't get all the way up. There are various accessories offered by Cosmo motors, but all talk about speed & say they may decrease acceleration but none talk about increasing the ability to go up hills.. There is an off road package that has a larger pulley and belt, would that make a difference? Any ideas appreciated!

Thanks! Barbara P : )

Barbara:

That is the bane of the single speed moped. You sometimes have to pedal on steeper hills. Don't force your engine on steep slopes or anytime it seems to labor. The engine can sieze. Back off the throttle slightly and continue. If you slow down to the point where you can pedal, you will have to.

The Kinetic Magnum with the variator drive would handle the hills with no problem.

If you want climbing power, you can get a bigger rear sprocket (more teeth on it, and bigger). Like if you have a 40 tooth, get a 45 tooth. It is kinda like a ten speed. the bigger sprocket/gear, the harder it is to peddle, but you get more power. Understand?

Honestly, though, there is no crime in pedeling a little bit :) We have to do it at one point or another.

A temporary solution that helps a little is to "tack" up the hill. It is somewhat like a sailboat zig zagging upstream. It turns a big hill in to several little ones. It takes a little practice and you have to be on a street or road where it is safe.

Make sure your spark plug is clean and properly gapped. Make sure your belt or drive chain is adjusted properly and make sure your tires are properly inflated. Also try a higher octane gas in your gas/oil mixture.

Check the spark plug first!

All these are little things you can do and may help.

The best hill climbing mopeds/nopeds I have are the Vespa Gande,the Puch Korado and my persoanl bike a Honda Urban Express. I weigh 220 and the Honda Urban will take me up about a 23 degree hill from a dead stop at the bottom. They are all 50 cc engines.

Good luck and Happy Trails (may all your hills be small ones)

Barbara,

It sounds like the larger pulley/belt combination would give you more low end power. The down side is that you lose top speed.

The rear sprocket option Chris offered would do the same thing but is probably harder to change and you would have to buy a longer chain.

Essentially, either of these changes just gives you a lower gear which you are then in permanently. This means better take off, more hill climbing power and lower top speed.

The "less throttle and pedal" option form Jim, is also good, especially if there are not too many hills.

If none of these are acceptable, you would have to look at a Biturbo and larger carb. This would allow you to lower the gearing without losing top speed. Others who have done this will probably post on the subject.

Like Ron said, a larger carb and biturbo is a good way to do it. My Maxi wouldn't take a hill for anything until I got a biturbo, and larger carb. Now it climbs hills fairly well. I still have to pedal if the hill is really steep, but it makes it up most inclines pretty easily.
