uneven/stop 'n go stand-up pedal stroke - help!

Hi, I set up my road bike in a Kinetic road machine trainer and I can't stand up and pedal. The stroke is uneven and I have to fight hard against the 'stop and go' of the pedal, usually unsuccessfully. This happened when I had my mountain bike in the trainer (with slick tires). I'm not sure if this is a trainer issue or a strength issue. I've no problem with this on the spin bikes at the gym or on my bikes outdoors. Help!

some things just are beyond a remote blind guessing keyboard ..
but here goes ..

your tire is probably slipping on the trainer roller

and there is nothing to be done but smooth out your pedal stroke

or get a trainer that is not using your bicycle wheel on it ..

those Lemond trainers replace your wheel so it wont slip because it's not used

the trainer flyweel-fan has its own cassette. air resistance wont be quiet..

I don't know that I can do that either. I think there is so little resistance on a trainer that things would happen too fast for me to be smooth. Is being able to do what you want something that people can generally do on a trainer?

I have the Kinetic Rock and Roll and have the same issue when standing, so I spent the winter seated. I was wondering if the Pro Flywheel that Kinetic sells, which adds about 12 pounds to the existing flywheel weight, would help with the standing problem. I will probably give it a try next winter.

<conceptually> another use for a Gates Belt system ... toothed trainer drums ..

again, eliminating the rear wheel, and the whole Cassette drive train, but allowing a magnetic or hydraylic resistance unit..

a higher friction interface of a roughened drum-roller on the usual trainer will tear up tires.
that wont make anyone happy ..


or.. As seen on TV ... http://www.amazon.com/ProForm-Tour-F.../dp/B005AEQ66S
$1500, down from $2K (noted: '3 at $1371.51')

A bigger flywheel would probably make tire slip worse.

Some things just don't work on a trainer. Standing up and hammering is one.

thanks for your replies.
I tried tightening the flywheel on the tire as my friend suggested but still can't stand and ride. Maybe it's time to accept that it just might not work.

Are you in too low of a gear so that there's not enough resistance ?
