City cyclists have worries enough during daylight — dodging cars, potholes, and roving dogs — that it’s a wonder any are daring enough to ride the streets at night. For those who do, Puma would love to supply a high-tech advantage: Although its name sounds like an oxymoron to us, the Stealth Visibility bike (pictured) aims to make riders hard to miss with a glow-in-the-dark paint job. Eager customers should note that it won’t glow all night and that you can’t keep it in a dark garage if you want it to soak up enough lumens to work. There’s also a frightening $1,600 price tag, though that does buy some features (tricky anti-theft and portability measures, for instance) in addition to the paint job. If you have any cash left, Puma offers a coordinating line of Urban Mobility Transit gear. Safety-minded riders on more restricted budgets can go the low-tech route with something like the Jogalite reflective yield symbol ($15) or buy a bit more flash with a pair of Pedalites ($80), the wide array of handlebar lights out there or battery-free packages made by Reelight that generate their own electricity from your pedal power ($40 to $65).
