Depends if you want to food shop on the way home from work, that's where racks and panniers are awesome.

Only thing I don't like about that huge basket bike is that the wheels are too close to...

I'm so used to seeing 50/34 now, what used to be normal 42, now looks to my eye like half-step.

I made a breakthrough in climbing standing (efficiency) when I figured out, to not be geared too low...

A-D: Nice classic bike. I see no triple crank, and also, is it me, or is the inner ring not a 42, but larger, closer to half-step gearing? Just curious. If you don't need the lows on the hills,...

I don't mind getting wet, and I wear raingear. I avoid biking in the rain because it trashes the drivetrain and the brakes with grit, and water can get in the hubs (poor seals), pedals (no seals at...

People have been working on bikes inverted, usually drive side facing you, for many decades without the benefit of a work stand. As long as you have decent chain tension, it should not affect your...

If you have a garage or other work area, what used to be expensive bike or kayak lifts, are like $8 at harbor freight or maybe amazon. Pulleys screwed into ceiling joist, two hooks for handlebars and...

I think the bigger problem is the lap-felled (4 thickness) double-sewn seams, expecially in the crotch.

There's a great program on NHK Japan, haven't seen it in a while, Cycling Around Japan,...

Bright green reflective vests are cheap, I'd recommend you buy one, I never bike without it. I use an XL so it will fit over warm clothes too. Best if the reflective strips are covered in clear...

Two additonal notes:

I have rim brakes on small 20" wheels, so I try to avoid long continuous braking, it heats the rims and can pop spokes due to expansion. So a particularly steep hill here that...

Ah yes, I ran it with 170 arms. Your longer arms cancels some or all of the effect of the taller tires, versus my calculation. I know gear-inch numbers well, haven't used gain-ratios, but should, as...
