large wheels on trikes
What are the pros and cons of having larger drive wheels on tadpole trikes.
The builder I am writing to said there are arguments both ways but I have not gotten his examples yet. If there are no reasons not to I would like to change the 20" wheel for a 26 just to get the small increase in speed. |

Pro: o easier to get high gears with standard components o /possibly/ slightly lower rolling resistance Con: o wheel less resistant to lateral forces o have to carry two different sizes of spare tube o harder to get low gears with standard components My trike has 406s all round. -- Dave Larrington - http://www.legslarry.beerdrinkers.co.uk/ It would appear apparent, to me at least, that dinosaurs were largely burrowing creatures. |

To this I would add a better ride with larger wheels. Yes, I am well aware frame design has a major influence on this, but my 24" and 26" trikes are smoother riding, and this contribute to their being faster than the 16/20 and 20/20 trike that I had before.By fast, I mean easy cruising in the high teens/low twenties. |

One other disadvantage of a large rear wheel on a trike is it requires the rear axle to be moved further behind the seat thus reducing the weight on the drive wheel and making the wheel more likely to spin on loose or slippery surfaces. Moving the rear axle back and lengthening the wheelbase does increase high speed stability though. My trikes have either 406s all round or 349s all round. They get enough wheel spin on wet climbs that I wouldn't want the rear axle further back. I also don't like carrying multiple sizes of spare tubes. Zach |
