The gear that actually matters for bike commuting

You don't need much equipment to bike-commute, but a few things make the difference between a good ride and a frustrating one. Here's what's worth investing in.

1. A helmet — non-negotiable.

A $40 helmet protects you about as well as a $200 one, but the kind of safety tech matters more than the price tag. Look for two things on the label: MIPS (a slip-plane layer that reduces rotational forces in a crash) and a rating from the Virginia Tech Helmet Lab, which independently star-rates helmets from 1 to 5. A 4- or 5-star MIPS helmet is plenty for daily commuting. Replace it after any crash, even if it looks fine.

2. Lights, front and rear.

Lights are the single biggest thing you can do for safety. Most crashes happen because a driver didn't see the cyclist, and visibility is most of the fix. Look for at least 200 lumens on the front, a steady-and-flash pattern on the back, and run them even during the day.

3. A real lock.

Cable locks get cut in seconds. A solid U-lock from Kryptonite or Abus runs $30-60 and pays for itself the first time you don't lose your bike.

4. A way to carry stuff.

This is the gear question that's most underestimated.

• Backpack — fine for short rides, but it'll make your back sweaty.
• Messenger bag — better airflow than a backpack, decent capacity.
• Panniers (bags that mount on a rear rack) — the most comfortable for daily commutes. Your back stays dry and you can carry a real load. Get waterproof ones or use rain covers; Boston rain is real.
• Basket — old-school, perfect for grocery runs.

5. Fenders if you ride in any weather.

A $25 fender set keeps a stripe of road grime off your back and pants. The single best rain-season investment.

Try this first

If you only buy two things, make them lights and a U-lock. Everything else can wait until you know what you actually need.
