Iv recently had the urge to get back into trials bicycling at the age of 80. i pulled my bicycle out of the garage and realized its not very good for front hooks, its a pennyfarthing. upon trying to hook a curb iv buckled my front wheel, do tryall make a 46'' front rim? prefferably drilled, big time? also has anbody got any suggestions on lowering my bottom bracket? iv already tried letting my tyres down. its a little high for the old pedal hop, i dont think the front wheel drive helps much, but i find it has an instant pick up. much better than a king.

i think koxx are looking into larger rims at the moment. hermance is currently riding the protype 46" rim which is drilled so will prob suit your style. as for bb try welding an extention down to a lower level then wear stilts while riding.. problem solved. what kinda brakes do you on that thing? rear maggie? front disc kinda setup. you must have to get a hose extension to get back to your rear wheel.

Hi i was researching this new rim too, over the last 15 years i have been constructing the worlds first trials trike designed for the disabled or people who just cant be bothered to learn how to ride a bike. i have used the frame of a 1978 townsend 'speed demon' and the rear axel off of a 1992 long wheel base ford 'transit'. the 26 inch wheel just didnt fit right and didnt cover the rear drums, so was looking into getting this new try-all rim as replacement, from what my resources have told me they are unvailing the new rim in the coventry branch of sainsburys, where vincent hermance is set to do a display outside the shop on the trolly's, should be good! also ive noticed that my trike ist handling to good any ideas on improving it? cheers

hi herman, ive recently discovered that by running an extra wide rear tyre off of a downhill microscooter helps to improve the balance when on the back wheel. some of my local crew have installed a snakeboard, its a genius creation that enables 3 wheel steering, just perfect for a bit of natural. i have started to favour riding with the stem backwars with a bouble ended pogo stick as an alternative for handlebars, by doing this i have found that when bailing sideways you bounce back up, this is a good trick in comp riding, reduces dabs! any ideas on new saddles currently running a 1932 rocking horse?

thanks for the tip cockyboy, i think that the pogosticks could be the next big thing! as for the saddle i have been working on something to be used on my trike, ive taken a standard office chair with a 360 turning capacity, covered it in luxurious shagpile carpet and welded it to the seat tube, this seat really comes in to its own when going fakey, you can just spin around for extra visibility, you sound like your more into the natural stuff so might not suit you at much. the thing which i am most having problems with is the drive system, i couldnt find a chain tesioner at hand so a chain just didnt sit right, i was handed the idea of using bailer twine by a local farmer who worships the stuff. it works like a dream chain pick up is instant resulting in huge gaps (personal best 37.2cm) however i think it looks a bit gash  what you think? |

hi herman
was jus wondering if that farmer happens to be clapperjoe?if not sorry. i think you may win a noble engineering prize with your seat idea. would suit a large number of riders. i no johnsonleberry has been looking for something like that for a while now. on my pennyfarthing dont have a problem with chain tension. however another solution is have a roller attached to your chain with a weight on it. i think about 1.23kg weight is about right giving a 3.45Nm tension. however if you crank it to hard it tends to getstuck in the front chain ring. this may improve your gaps by prob 10%. i having issues finding the correct bearings for my front wheel. HELP!

one of the chaps who iv been sessioning with, Chris 3 has much experience in the world of trikes, hes had some sick bails recently with some serious consequences as a result of the bailer twine jus not holding out on the gap to manuals. i have been doing some of my own work on this and found that a well tentioned ratchet strap works well, looks better and there is even the posibility of a freecoaster upgrade that im currently workin on. the chair solution sounds spot bollock, any local retailers? any ideas on fitting a wheely bar?

Solution!!! i have previously had the bearing problem on pennyfarthing and found that the ones within my wifes rampant rabbit work well. alternativly u could go for less bearings and use the stones from peaches? iv found these less smooth and prone to cracking. ever though of moding a robbin reliant into a super trike?

i will try the ratchet strap out tomorrow in my workshop sounds like it could be the answer that im looking for as for the wheely bar,my 'trannytrike' has yet to do one so cant coment need to get somemore strength in my arms. also i see in an earlier post you were having troubles with your brakes and having to use your feet as a stopping device..i have to admit this is a hard habbit to get out of as it works so well  , but if you want to avoid getting brake dust on your best pair of slippers i now use a number of sticks stored in a front loading basket i have attached to my bars. tend to use around 560 sticks per ride, but worth it for the stopping power |

cheers for the brake solution, sounds like it might even beat my method of throwing the old zimmer frame in the front wheel. any particular kind of sticks? or just fresh out the hedgerow? iv temperarely fixed my buckled front wheel with the use of a old horse cart wheel, bit on the heavy side but think it should be strong enough to handle my style. slight lack of tracktion as has no rubber, any ideas?
