Bike with a rear cargo bag

GPS TrackersFeatured

Apple AirTag (with hidden bike mount)

An AirTag is not a GPS tracker — it relies on nearby iPhones to report its location through the Find My network — but in a populated area like the Dallas suburbs that network is dense enough to locate a stolen e-bike surprisingly often. The trick is hiding it: under the saddle in a purpose-made mount, inside a bell-shaped mount, in a reflector housing or under a bottle cage. Thieves know to look, so pick a mount that is not obvious. Battery life is about a year on a coin cell. Android users should look at Tile or a Google Find My Device tracker instead.

Best for: iPhone owners · Urban and suburban parking · Pairing with a good lock

E-Bike LocksFeatured

Kryptonite Evolution Mini-7 U-Lock with FlexFrame Bracket

The Evolution Mini-7 is the practical middle ground: a 13 mm hardened shackle that resists most bolt cutters, a 7-inch opening that actually fits around a wheel and rack, and a frame bracket so it rides on the bike instead of in a backpack. Many listings bundle a braided cable for the front wheel. It is lighter than the New York series and a good match for a commuter e-bike worth one to two thousand dollars parked in moderate-risk spots. For overnight outdoor parking in a city you will want to step up to an 18 mm shackle or pair this with a chain.

Best for: Daily commuters in suburban and campus settings · Riders who want the lock mounted to the frame · Mid-value e-bikes

E-Bike LocksFeatured

Kryptonite New York Fahgettaboudit Mini U-Lock

This is the lock to buy when the bike costs more than the rent. The Fahgettaboudit Mini uses an 18 mm hardened steel shackle with a double-deadbolt crossbar, which puts it in the small group of locks that shrug off bolt cutters and force attackers to use a grinder and time. The mini shackle is deliberately small so there is little room to fit a jack or pry bar. The trade-off is that small opening: you will not lock both frame and wheel to a fat pole with it, and it is heavy enough that many owners leave it at the office rack and carry something lighter for quick stops.

Best for: High-value e-bikes locked outdoors · Urban and campus parking with theft pressure · Riders who leave the bike in one spot all day

Phone MountsFeatured

Quad Lock Out Front Bike Mount

Quad Lock's twist-lock system is the standard most other mounts are measured against, and the Out Front version places the phone ahead of the stem where it sits level and easy to read. You need a Quad Lock case or universal adapter for your phone, which is the main catch and the main strength: the lock is positive, vibration-tolerant, and does not rely on clamps that loosen over potholes. For e-bikes with heavy vibration or fat tires, add the optional vibration dampener to protect camera stabilization hardware. The arm clamps 31.8 mm or 35 mm bars depending on the version.

Best for: Riders who navigate on the phone daily · E-bikes with cluttered cockpits · Phones in Quad Lock cases already

E-Bike Locks

ABUS Bordo Granit XPlus 6500 Folding Lock

Folding locks solve the problem U-locks have on e-bikes: fat tubes, rear racks and awkward parking posts. The Bordo 6500 uses thick hardened-steel links with protected rivets, packs into a holster that bolts to bottle bosses or straps to the frame, and opens wide enough to wrap a wheel, frame and pole together. It is among the strongest folding locks tested, though any folding design still gives up some security to a good 18 mm U-lock at the rivets. For e-bikes parked during the workday or at a campus rack, the combination of reach and carry convenience is why it sells so well.

Best for: E-bikes with fat tubes that U-locks cannot reach around · Commuters who want a lock that lives on the frame · Locking to odd-shaped racks and posts

E-Bike Locks

ABUS Granit XPlus 540 U-Lock

ABUS's Granit XPlus 540 is a favorite among shop mechanics because it hits a sweet spot: a 13 mm square-profile shackle that is tougher than its diameter suggests, a lock body that is noticeably lighter than 18 mm monsters, and an XPlus disc cylinder that resists picking well. It comes in a couple of shackle lengths, and the longer one is handy for e-bikes with fat downtubes and wide racks. ABUS includes a frame bracket. It is one of the highest-rated locks in its weight class, making it a solid pick for commuters who want better-than-average protection without carrying a dumbbell.

Best for: Commuters who park in mixed-risk areas · Riders who dislike the weight of 18 mm locks · E-bikes with wide tubes that need a longer shackle

Rear Racks

Blackburn Outpost Fat Bike Rear Rack

Fat-tire e-bikes are the fastest-growing segment and most standard racks simply do not fit around a 4-inch tire. Blackburn's Outpost Fat Bike rack is built wide and tall for fat tires up to roughly 5 inches, adjusts for wheel size, and mounts to eyelets or with included clamps where eyelets are missing. It is a touring-grade rack with a solid load rating and a top platform for dry bags. On fat-tire e-bikes the challenge is the rear hub motor width and wiring, so confirm the rack legs clear your dropouts and torque arm before committing.

Best for: Fat-tire e-bikes without a stock rack · Bikepacking and hunting setups · Riders needing a wide platform

Water Bottles & Cages

CamelBak Podium Chill Insulated Bottle (21 oz)

In a Frisco July the difference between a plain bottle and an insulated one is whether the water is drinkable after twenty minutes. The Podium Chill is a double-wall squeeze bottle with a self-sealing jet valve that does not leak in a bag and opens when you squeeze. It fits standard cages, though the insulated version is a bit stiffer to squeeze than the plain Podium. It is dishwasher safe. It is one of the more common bottles you will see on e-bikes precisely because it is simple, cheap and keeps drinks cool for about as long as a neighborhood ride lasts.

Best for: Hot-weather riders · Commuters and neighborhood loops · Bags and backpacks (no leaks)

E-Bike Locks

Foldylock Compact Folding Lock

The Foldylock Compact is a lighter, less expensive folding lock that still earned a Sold Secure rating and comes with a tidy frame case. It is a good match for riders who stop at shops and cafes several times a day and want something they will actually reach for instead of rolling the dice on a cable. The links open wide enough for most e-bike frames plus a wheel and a rack, and the keyed cylinder is better than the bargain folding locks flooding the market. It is not in the same class as the ABUS 6500 for serious theft pressure, so treat it as a mid-risk lock.

Best for: Quick stops and errands · Suburban and campus parking · Riders who want light weight over maximum security

E-Bike Helmets

Giro Register MIPS Helmet

The Register is the helmet we point people to when they want real rotational protection and do not want to think about sizing. Giro ships it in a single universal adult size with a wide-range dial, adds MIPS, and keeps the price near the bottom of the MIPS market. Ventilation is generous for the money, the visor snaps off, and replacement pads are easy to find. It is a recreational lid rather than a commuter-specific design, so there is no light mount or vent shutter. For neighborhood loops, campus rides and casual weekend miles it is hard to beat on value.

Best for: Budget-conscious riders who still want MIPS · Households buying several helmets at once · Casual neighborhood and campus riding

Security Alarms

Knog Scout Bike Alarm & Finder

The Knog Scout does two jobs: it is a motion alarm that screams when the bike is moved, and it is an Apple Find My device so you can locate it like an AirTag. It bolts to the bottle-cage bosses with security screws and is controlled from the Knog app. The alarm is loud enough to make a thief reconsider a quick grab, and it arms and disarms automatically as your phone comes and goes. It is iPhone-only for the Find My function. Rechargeable via USB-C. It works best as a layer on top of a real lock, not a substitute.

Best for: iPhone users who want alarm plus location · Bikes parked briefly outside shops · Tamper deterrence

Phone Mounts

Lamicall Bike Phone Holder (clamp style)

Lamicall's clamp-style holder represents the large category of universal mounts that grip the phone with spring-loaded arms and need no special case. It is the easy, cheap answer for riders who do not want to commit to an ecosystem, and for loaner bikes, kids' bikes or a second e-bike. The phone can rotate to landscape and the clamp fits most bars. The honest downside of every clamp mount is the same: vibration from fat tires and rough pavement can loosen the grip over time, and the arms cover part of the screen edges. Tighten it, check it, and do not use it on technical trails.

Best for: Budget shoppers · Riders who change phones or cases often · Casual neighborhood rides

E-Bike Helmets

Lumos Ultra Smart Helmet

Lumos put a bright front light, a wraparound rear light, and optional turn signals into a helmet that looks surprisingly normal. The Ultra is the mainstream model: lighter and better vented than the original Kickstart, with a wireless handlebar remote for signals and brake lights that react to the helmet's motion. The lights do not replace a proper handlebar headlight for seeing the road, but they put visibility at driver eye level. MIPS is available on some variants. Battery life is measured in hours, not days, so it becomes one more thing to plug in alongside the bike.

Best for: Urban commuters riding at dusk and dawn · Riders who want turn signals without wiring the bike · Visibility-first shoppers

Gloves

Pearl Izumi Elite Gel Gloves

Hand numbness is a common complaint on e-bikes because upright riders put steady pressure on the same spot of the palm. The Elite Gel is a half-finger summer glove with gel pads placed over the ulnar nerve area, a wicking back, and a pull-tab to get them off. It is cooler than a full-finger glove and the padding takes the sting out of chip-seal roads and trail vibration. The gel is moderate rather than thick, which most riders prefer. It runs true to size. It will not protect fingertips in a crash the way a full-finger glove does.

Best for: Riders with hand numbness · Hot-weather commuting · Cruiser and upright bikes

Reflective Equipment

Salzmann 3M Scotchlite Reflective Ankle Bands

Moving reflectors catch a driver's eye better than static ones, which is why reflective ankle bands are one of the most effective cheap safety items you can buy. Salzmann's bands use 3M Scotchlite material, wrap with hook-and-loop, and double as pant-leg straps to keep trousers out of the chain. On an e-bike you may pedal less, but the bands still move and still mark you as a cyclist. They are light enough to live in a bag year-round. Buy a pair for each bike or commuter in the house; they are inexpensive enough.

Best for: Every commuter · Keeping pant legs clear of the chain · Adding motion reflectivity

Security Alarms

Wsdcam Wireless Bike Alarm with Remote

This is the archetype of the inexpensive vibration alarm sold widely online: a small box that straps or bolts to the frame, a key-fob remote to arm and disarm, adjustable sensitivity and a loud siren. It costs very little, runs on a rechargeable battery or coin cells depending on the version, and will startle a casual thief. It is also prone to false alarms in wind or when a bike rack neighbor bumps you until you dial the sensitivity down. Treat it as a deterrent layer for low-risk parking — not as security on its own.

Best for: Budget theft deterrence · Garage or apartment bike rooms · Kids' and secondary bikes
