View Full Version : SpinCycle hard to pedal

Hey everyone, I've been lurking for awhile, but am just now making my first post. I bought some of the bike plans awhile ago and have been having fun tearing apart bikes.

I just finished the SpinCycle. It was a lot of fun to build and I couldn't wait to ride it. I'm having a problem with pedaling though. It is really hard to pedal, and I can't figure out why. I used a 20" bike for the forks, chain stays, wheel, and crank set.

I know a picture would help a ton. I'll post one in a little while when I get back to the shop. I tried looking through the forums but wasn't really finding anything.
TIA for any help or tips you guys have. I can't wait to get this going! I'm hoping to build one for my kids as well. They love all the videos I've shown them of it

A picture says a thousand words , see the advice on posting pictures at the top of the page ,

what happens if you turn it upside down and pedal it by hand - either gearing or tight component .

Here's a couple pictures from the first go at it. It was really hard to pedal then, so I cut it apart and changed the angles a bit. It's still really hard to pedal.
If I lift it off the ground and turn the pedals by hand they turn fairly easy.

hi there

Not built one yet but do know the beast from reading the Brads books etc

Couple points ?

In normal bike terms that gearing looks to be a 'high' gear at the wheel end ?
Could you either get less teeth at the pedals or more teeth at the wheel ?

Chain on wrong side ? does that mean there is no freewheel ?

Should the castors be at an angle to the frame ? also they looks a little small in diameter ?

keep at it , it looks the part and should be easy to fix ?

Thanks for the replies!
The chain is on the right side. I made the mistake of putting it on the wrong side the first time I put it together. Lol.
The casters are at about a 5 degree angle now. In these pics they were off quite a bit. When I cut it apart to try to fix it I made sure that the caster bar was at the 3-5 degree mark.
The casters are 4" ones that I got at harbor freight.

I'll try to find a different gear to put on the crank and see if that helps.

I appreciate everyone's tips!

Here's the latest pictures of the spincycle. I haven't tried switching out the gear on the crank set with a smaller one yet, hopefully get to that tomorrow

May I be so bold as to suggest a 5 or 6 speed freewheel and gears , this would give a range of gears , sirjoey a contributor of a few years ago made one with 3 x 20" wheels and gears it was quite quick as well , aim for a max of 2:1 gearing certainly much less than 3:1 on 20 " wheels .

The type of fun with a spin cycle is acceleration not top speed.

Thank you Paul and Emma for your advice! I was able to play around with it a little bit today. I found a smaller chainring and put that on as well as making sure the bearings were in the correct way and well greased. I didn't have much time to play with it when I was done, but it did seem to pedal easier. My 11 year old daughter was even able to pedal it a little bit. Would have been easier for her if she could have reached the pedals better.

Now she wants me to build one for her. I'm assuming to build a smaller one you would just use a smaller fork and wheel, and then adjust the lengths of tubing to fit?

18 " or 16 " front wheel ( back end off a small bike ) the main problem is the leg length and what damage a wheel could do . Dads know best !

I think I have an old 16" bike. Might be time to tear it apart and build her one when I get this one finished.

Thanks again for all of your advice! This has been so much fun!
