TiRush seat adjustment

I love my TiRush, but occassionally I need to adjust the seat, because of the different shoes that I wear. It seems quite awkward to have to untighten two bolts under the seat, loosen the back brace, and then try and get the seat to move a little (it doesn't slide very easy), and finally tighten things up. Has anyone come up with a better system for adjusting the seat?

Don't know if this would work or not, but you could try just tilting the back a bit more and leaving the base as it is. On some bikes I have owned, this had the same affect as moving the whole seat back.

Try loosening the hose clamps that hold the back to the base. I find this makes the seat base move easier by allowing the base/back angle to change more easily than does loosening the seat braces only. Also, lift up on the base a bit and wiggle it side to side as you move it forward or back.

Been fiddling with mine in the garage the last two nights 8-).

Thanks for the ideas. It doesn't appear that there is any magic answer. Easyracers response was that any quick release system would not hold the seat in place as firmly as the current set up. The seat does need to be lifted up and wiggled to get it to move when I adjust it, and this makes it difficult to move it just a little bit. If there were markings on the bottom so that you could see how much it has moved that might help. I could put the markings on myself, but it would be nice if the bike came with the markings.

Max,

An easy way to mark your current seat position is to 1) measure from the nose of the seat to the crux of the head tube/top tube and 2) measure the amount of back support rod showing past the clamp. Remember to write these numbers down.

I too have wondered about a measuring system for seat position. What I intend to do is get a "stick on measuring tape" used by wood workers and such. They would stick it to a bench, or on a tool table. Mine is 36" long, and durable plastic. I'll stick it to the square tube "seat adjustment tube" on the EZ Sport. Perhaps the TiRush has a similar arrangement?

Details: I'll run the seat all the way forward till the front cam clamp is a the edge of the square tube, & mark the spot with masking tape. Then run the seat all the way aft, mark with tape. Next remove the seat. I'll put the masking and measuring tape on the kickstand side. Clean the square tube with alcohol. Cut the tape to fit beyond the tape marks and inch or so. Then stick the tape to the side of the square tube up close to the top. Avoid the radius edge where the top flat meets the side flat-tape is too stiff to stick around the radius. Burnish it on. Replace the seat & enjoy.

Why mount at the top of tube side? On EZ Sport, the cam clamp pinches the seat slide at the bottom, so the tape should wear better by locating it near the top.

Why would I want a measuring system? 1) let other people ride the Sport, try to get them hooked. 2) After they ride, I can easily return it to my perferred position! 3) while I'm trying to find my perferred position, I can easily move the seat by a 1/4" or so and test the adjustment. Get some data!--george
