Cycling

When using an interactive cycling program, the rider's real-life bike usually just sits flat, regardless of changes in the onscreen terrain. The Rizer, however, tilts the bicycle up and down to match the program's hills and valleys.

Although different saddle angles are better for different cycling scenarios, most riders aren't likely to stop and adjust that angle every time the terrain changes. Aenomaly Constructs' SwitchGrade, however, allows them to do so quickly and easily.

It can be frustrating, trying to carry a DSLR within easy reach while cycling. The Makers in Motion Camera Strap is designed to help, by keeping the camera out of the way when riding, but allowing it to easily be grabbed when needed.

While cyclists certainly don't like getting flats, puncture-resistant tires are typically heavier than others. According to French manufacturer Hutchinson, however, its Gridskin tires combine durability with light weight – and less production waste.

A large percentage of bike-versus-car accidents occur when automobiles pass too closely to cyclists. The Dashbike tail light was designed with that in mind, as it automatically records video of any too-close drive-bys.

Why just wear a plain ol' bike helmet, when you can wear one with a built-in headlight, tail lights, turn indicators and brake light? That's the thinking behind the Lumos Ultra, which I recently had the chance to try out on real-world roads.

While many cyclists use apps such as Google Maps to navigate city streets, glancing down at that cluttered map display can be confusing. The Beeline Velo 2, however, is designed to keep things simple and easy to read.

While it looks like a relatively normal polyester shell cycling jacket, the Cirrus has a trick up its sleeve. In the event of a collision or fall it transforms into a wearable airbag, inflating in just 0.08 seconds to protect the neck and body.

Checking your bike's tire pressure can be a fiddly process, which is why there are now valve stem attachments that let you check it with your smartphone. The just-announced PSIcle sensor makes things even easier, as it doesn't require a battery.

Six years ago, Chinese manufacturer Livall debuted one of the first "smart" bicycle helmets. Well, the company is still at it, with a lighter, sleeker new model that's currently on Indiegogo.

Combining attributes of both road and mountain bikes, gravel bikes are becoming an increasingly common sight. So, what if you want one that still manages to look a bit … different? Well, the new Urwahn Acros might be a good choice.

In order to keep drivers from passing too close, some cyclists use bike-mounted foam "noodles" that extend out horizontally toward the traffic. The L-Bow takes that concept a step further, by applying it to a tail light.
