need hill climbing advice
Thanks for all the advise about hill climbing. I can't quite get it right when trying to start (again) after stopping on a hill. I am new at this and have been working on free mounting the coker and on a good day it takes two to several attempts to get started on the level. but Up hill is a different story I usually after @ 5 min. of trying just push the uni to the top and start again.

I want to get an odometer for my 36 inch wheel, any suggestions? I have a cat eye wireless for my fixed gear and wanted to use that but the calibration rations only go up to 700mm. Thanks , also any one in the Pittsburgh Area, see you at the Mon wharf 1 Jan 2009 for the polar bear dip. We will be selling T shirts "Polar bears For Bundle up" All the proceeds go to project bundle up - get cold to help a kid stay warm!

Starting up-hill is very challenging, with the difficulty increasing swiftly with the steepness of the hill. If you can't mount uphill then turn around, mount down-hill, and do a quick u-turn. It's allowed. Or mount across the hill, perhaps from a driveway. -- Bruce Dawson ------------------------------------------------------------------------ Bruce Dawson's Profile: http://www.unicyclist.com/profile/1299 View this thread: http://www.unicyclist.com/thread/58221 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Bruce Dawson;1158480 wrote: Therefore the steepest hill that can be climbed if you apply just your weight to the pedals with 6" cranks on a 36" wheel is somewhat less than a 2/3pi grade or 21%. I realized today that the physics is a bit more complicated than I made it sound. The 2/3pi grade calculation assumes that you are applying your full bodyweight to the forward pedal at all times. You can, surprisingly, do better than that. If you effectively 'jump' from one pedal to the other then you can apply several times your body weight to the pedal when it is horizontal, and not waste any body weight when the pedal is near vertical. This averages out to being equivalent to always applying your full weight to a horizontal pedal. This means that the maximum grade that can be climbed without pulling on the seat, assuming a zero-weight unicycle and perfect riding skills, is 33%. I'd love to hook up force meters to the pedals and the handlebars and see what actually happens when an expert rider climbs a steep hill. -- Bruce Dawson ------------------------------------------------------------------------ Bruce Dawson's Profile: http://www.unicyclist.com/profile/1299 View this thread: http://www.unicyclist.com/thread/58221 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

It is much easier to go up a hill by going from side to side. Why bother stressing out the legs and lungs. The first guy I ever saw on a uni went from side to side and by the time he arrived at the top he said he felt fine. ANY hill can be conquered by riding side to side. I think sailors call it tacking!! -- dtecum You can't always believe a word I say.

I think sailors call it tacking!! I think there might be more energy lost in the act of turning than in just driving straight on up the middle of the sucker. Especially on a Coker-type uni, tacking up into a steep hill and back across to the other diagonal is brutal. As mentioned, if a hill gets steep, you hold on tight and jump hard (i.e. more than your weight) on the uni's front pedal. -- steveyo steveyo ...like having your own personal rollercoaster... - a 'few uni race write-ups' (http://home.roadrunner.com/~rduhan/uni_race_writeups/) - muni and kokopelli uni 't-shirts, mugs and stickers' (http://www.cafepress.com/steveyo) ------------------------------------------------------------------------ steveyo's Profile: http://www.unicyclist.com/profile/7228 View this thread: http://www.unicyclist.com/thread/58221 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

They can have signal problems if you ride w/ others they can get their signals crossed and you have to keep the computer really close to the pick-up on the fork leg. Besides you can't check it on the fly. I'd get a wrist GPS. MuniAddict has one, ask him where he got it. -- skilewis74 Ride everywhere and never just ride anywhere.

need hill climbing advice
with freemounting big wheels hill-climbing is my weak spot this is curious since I am fairly good at it on a MTB. Again I suspect I am not relaxed enough and spend too much energy: it's not my legs that give up it's my lungs : effort asthma starts there and I start mewing like a dying cat! curiously I can climb longer with 125 cranks on a 20" or 29" wheel than with 145 cranks on a 24" (dead spot?) -- wobbling bear One Wheel : bear necessity ------------------------------------------------------------------------ wobbling bear's Profile: http://www.unicyclist.com/profile/3716 View this thread: http://www.unicyclist.com/thread/58221 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

It's the last point on my climbing tutorial. How much leverage you need is obviously dependent on the terrain and the rider, but if you use an extreme example: imagine riding on 400mm long cranks. Plenty of leverage, but unless you are 3m tall, it's probably not going to be very efficient at climbing. -- GizmoDuck The Induni Unicycle Tour 2009. Unicycle Tour of India.
