Best GPS Bike Computer
Wahoo Fitness ELEMNT ROAM GPS Cycling Computer
Display size 2.7 inches
Battery USB rechargeable
Battery life 17 hours
Weight 3.3 oz.
A GPS bike computer gives you the freedom to explore without worrying that a wrong turn will lead to an unplanned all-day adventure. So, whether you like to navigate on the fly or prefer plotting out turn-by-turn directions, the Wahoo Fitness ELEMNT ROAM GPS Cycling Computer will help guide you home. A high-contrast color display and 2.7-inch screen make it easy to page through all your vital stats like speed, distance, lap time, heart rate, elevation and more. And it's compatible with several smart trainers and many data-tracking apps, too, including mountain bike trail integrations. “The user interface on the phone app is intuitive, easy to use and just works really well,” says Kevin Lau, a retail specialist at the REI store in Marlton, New Jersey. With 17 hours of battery life tucked into one easy-to-use device, you may find this bike computer a highly capable stand-in for your map-savvy riding buddy—except the ROAM won't share its snacks with you, no matter how nicely you ask. Buy here.
Best Bike Phone Mount
Nite Ize Squeeze Rotating Smartphone Bar Mount
Dimensions 3.27" x 4.33" x 2.36"
Mount style Tool-free
Compatible with Phones from 2.3 to 3.6 inches (with or without a case)
Weight 3.7 ounces
If you prefer the all-in-one convenience of having both maps and apps at your fingertips, the Squeeze Rotating Smartphone Bar Mount from Nite Ize is a secure way to mount your phone out front for on-the-go communication. A sturdy rubber strap attaches to your bike handlebars (or to jogging strollers, wheelchairs or even grocery carts) quickly and easily, while continuous-force springs actuated by “squeeze arms” securely hold your phone in either landscape or portrait mode. “It’s easy to pop your phone into the mount,” says Lau, the REI retail specialist. “It works really well and is great for commuters.” We like this mount because it holds gadgets from 2.3 to 3.6 inches wide (which includes most phones), though some users reported experiencing trouble fitting phones with thicker cases. The tool-free mount system is sturdy enough to handle even bumpy off-road rides and the exploits of curb-hoppers. Buy here.
Best Water Bottle Cage
Bontrager Bat Cage Water Bottle Cage
Weight 48 grams
Materials Recycled plastic from fishing nets
A longtime customer favorite, Bontrager’s best-selling Bat Cage Water Bottle Cage is back—and better than before, as it’s now made from recycled ocean plastics. Each year, about 8 million metric tons of plastic makes its way to the ocean, polluting beaches and bodies of water worldwide. A significant part of that plastic waste is fishing nets. Bontrager partners with Bureo, which collects end-of-life ocean fishing nets in Chile and recycles them into plastic pellets. The pellets are used by a number of outdoor gear companies, including Bontrager, which turns them into the Bat Cage. The result: a lightweight, durable bottle cage that holds your drink securely and cuts down on plastic waste. “Perfect,” says one customer reviewer, who bought the Bat Cage to replace a metal holder that was too large. “This one is pliable and hugs the bottle, keeping it rattle-free and snug.” Buy here.
Best Frame-Mounted Bike Pump
Silca Tattico Mini Pump
Size 9.5 x 1 inches
Weight 5.5 oz.
Maximum pressure 100 pounds/square inch
Valve type Presta, Schrader
Flats happen—to everyone, eventually—but having a mini pump and a spare tube on you can be the difference between a short delay and game over. That said, hand pumps are finicky. The Tattico Mini Pump from Silca fixes many common mini pump gripes (It’s too big to carry! It doesn’t pump enough air! Help! I just sheared off my valve stem!) with a super-compact inverted design with the hose and valve hidden inside an inner chamber. That means you get up to 10% more air per pump, reducing the time it takes to get you back on the road.
Adjustable rubber cup seals expand to reduce leaks as the pump heats up from use, while the lever-actuated chuck (with Presta, Schrader or Dunlop valves) is attached via flexible hose, so you won't accidentally decapitate your valve stem with a too-vigorous pump. Sweaty-palmed users love the knurled aluminum barrel for extra grip, and the compact size (and included frame mount) means you'll be the one on the group ride boasting, “Mini pump? Oh, you know I got that thing on me!” the next time someone gets a flat. Buy here.
Best Bike Floor Pump
Topeak JoeBlow Sport III Bike Floor Pump
Dimensions 26.7 x 10 x 4.6 inches
Maximum pressure 160 pounds per square inch
Valve type Presta, Schrader and Dunlop valves
You won’t get very far with underinflated tires, and since you should ideally check your tire pressure before every ride, a floor pump is an essential tool for your kit. If you're simply looking to get out the door as quickly as possible, the JoeBlow Sport III from Topeak is a real workhorse, with an easy-to-read pressure gauge and a double-headed pump head that fits Presta, Schrader and Dunlop valves. It’s “the tried-and-true pump that does everything you’d want,” says Aaron Potvin, REI's assistant category merchandiser for cycle accessories. Buy here.
If, however, you’re looking for a floor pump that’s a joy to use and looks good enough to store in your living room, the Pista Plus Floor Pump from Silca blows away the competition. The lathe-turned ash handle feels sturdy and luxurious underhand, while the Italian leather cup seal and full metal piston assembly pumps air with great efficiency—perhaps a little too efficiently, given the pleasure you’ll derive from using this pump. Bonus: It looks so sleek there’s a good chance you’ll be able to pass the Silca down to your grandkids, so take that into consideration when comparing price tags. Buy here.
Best Bike Lock
Kryptonite New-U Evolution Lite Mini-6 U-Lock
Lock type Key lock
Dimensions 6.5 x 2.75 inches
Weight 1 lb. 9.5 oz.
Give a thief enough time, privacy and the right tools, and—poof!—your bike may be a distant memory. The New-U Evolution Lite Mini-6 from Kryptonite is relatively light but features an 11-millimeter steel shackle to secure both your frame and your wheel to a bike rack. The double-bolting mechanism holds the shackle on both ends while still featuring the familiar, easy-to-use angled closure of other Kryptonite U-locks. “Never had an issue and it doesn’t feel like you have an anvil in your bag,” says one customer reviewer. For jaunts during daylight hours or brief stopovers where a beefy-looking U-Lock is enough to deter most would-be criminals, our staff doesn't go without this one. Buy here.
Best Bike Fenders
Portland Design Works Full Metal Fenders - 700c x 45 mm
Best for Road bikes, gravel bikes, or urban commuters
Max tire width 35 mm
Recommended wheel size 700C
Weight 510 g
If you're committed to getting out there on two wheels no matter the weather—or just have a knack for getting caught in the rain—a set of fenders can really save your rear, as well as the face of the rider behind you. A set of Full Metal Fenders from Portland Design Works provides coverage to help keep both you and your bike cleaner and drier. One REI staffer uses his set on a gravel bike in winter, and raves that they're easy to install, stay in position and "will hold up in nasty conditions." Best suited for gravel and road bikes with tires up to 35 millimeters wide, the fenders’ full-wrap design and extra-long rubber mud flaps shed muck effortlessly, while safety release tabs mean that built-up debris between the tire and the fender won't bring you to a screeching halt. The installation is straightforward, and the kit includes the hardware you need to mount these to most frames. Buy here.
Bike Accessories Buying Advice
Many buying decisions in the bike world boil down to simple math: Is it worth the weight? A similar concept applies when considering what accessories you might want to trick out your ride, but the proper equation to run here is: What’s the enjoyment-to-weight ratio?The same concept comes into play when considering the accessories you might want to trick out your ride: What's the enjoyment-to-weight ratio? For some riders, only the basics make the cut, like the essentials you need to fix a flat tire. Other riders don’t mind extra weight if it makes the ride more comfortable, enjoyable or otherwise just subjectively better. We think all the above make the cut.
Most of our picks address the needs of all riders, whether you're a diehard mountain biker, a dedicated gravel grinder, or an urban commuter. As noted above, every rider flats eventually, and everyone needs a multi-tool, water bottle cage and floor pump. That said, you may find that full fenders are overkill on a road bike, or that you're fine tucking your phone into a pocket while riding. You do you.
