Re: Possible 30% Income Tax Credit For The Purchase Of An Electric Bike (U.S.)
It would be interesting if Congress passed an eBike incentive. Why not a tax break for people who never leave the house and go outside? They aren't burning ant fossil fuels at all for travel. A sofa incentive would be nice. June 25, 2022, 10:55:28 AM |

Re: Why are road bikes more popular than mountain biking?
But surely most people who can afford a $2000 bike also live near a park? So they can throw the bike in their SUV and drive to the trails? I live in a place where trails are just a bike away. I was a competitive XC MTB guy before switching fully to road bike. I also used my MTB to go to various places and train in paved hills or mountains. Then I bought a road bike and was planning to just use it for road work and do trails on MTB. But then, road biking is much more fun in paved roads and much faster that I gave up my MTB and sold it to buy a nice Chiner frame. Well the thing is, I understand why road biking is more popular than MTB. Lot of people just want to go from point A to point B using bike and the fastest way to do it is on a road bike. Maybe another thing is, road bike races are much more exciting to watch than XC MTB. On road bike race, you need to factor in a lot of things and there's a team work and there's a lot of strong riders on the field and is not just dominated by one person. Meanwhile, on XC MTB, I know only 2 people who is really strong they dominated XC MTB for a decade each and that was Julien Absalon and Nino Schurter. On XC MTB races, the one who goes first on single track is usually the winner and casual riders don't want to watch a single guy riding solo on a breakaway. This is just my opinion :p December 16, 2023, 07:35:59 PM |

Re: Chinese gear that measure the power output of both legs in watts?
The power meter (single side or dual side) measures the power, the computer just displays the results. Racers usually use the smaller computer like the 840 or Bolt V2. Igpsport 630 is a popular Chinese computer. Crank or portal meters come in single or dual versions. A popular Chinese power meter is the spider type Magene P505, which measures both sides.

Re: Chinese gear that measure the power output of both legs in watts?
Spider based power meters are really not good at estimating left/right balance. They can't differentiate between power the left side pulling and right side pushing, and vice versa. I tested this several times, for instance you can unclip your left leg and cycle only with your right leg. The L/R balance should be 0% / 100% (and my Favero Assioma pedals confirm that)... but the spider based power meter will estimate the L/R power based on how much pulling up you do with the right leg, and assign that to left side power, and pushing down with the right leg will be assigned to right side power. So it is basically useless. Only crank based or pedal based power meter can accurately measure L/R balance. December 26, 2023, 08:30:56 AM |

Re: Chinese gear that measure the power output of both legs in watts?
It matters quite a lot. In my case my left leg was always "a bit lazy". When I try to do single leg drills, right leg is very smooth, but left one feels like pedaling squares. On my Assiomas measured L/R balance is 45/55 (also confirmed on friends Garmin Vectors). But spider based power meter reports L/R balance at 53/47. I assume that because my left leg does almost no pulling, and right one does some, the interpretation is completely wrong in the end. So yeah, L/R estimation on anything that is not pedal or crank based, is completely useless. December 26, 2023, 12:48:05 PM |

Re: Chinese gear that measure the power output of both legs in watts?
For any normal case, a spider is fine. If one leg is pedalling squares and the other circles, then you got deeper issues than your power meter.

Re: Chinese gear that measure the power output of both legs in watts?
Its not so much about "pulling" as it is just unloading the pedal on the way up. I find it quite natural on the right side, I don't have to even think about it. Sometimes when I ride a bike with flat pedals I notice that my right leg gets a bit of "air time" on the upstroke. But the left leg was never like that. No injuries, no conditions, same leg length... its just "lazy".

Re: Why are road bikes more popular than mountain biking?
It's actually other way around where I live - MTBs are far more popular than road bikes, even among people who ride in the city Similar situation here. There is a MTB trail system on my road and the parking lot is always packed weather permitted. I rarely see other people out cycling on roads, and I live in a 'gravel mecca' (Vermont). Something that keeps me from getting into MTB is that I'm afraid of injuring myself, it seems prerequisite to have a major crash for MTBers (at least more so than road cyclists) and the trails here are quite technical.

Re: Inexpensive Torque Wrenches
Are digital torque wrenches useful? I think they might be more of an "idiot-proof" way to make sure you don't destroy your carbon bike lol I'm so happy of mine for this exact same reason. However I'm not sure it should be re-calibrated, from time to time. I just asked SHAHE about it. December 31, 2023, 05:18:50 AM |
