The bike gets you moving; the accessories keep you moving. A $1,000 ebike with a $20 cable lock and no lights is a theft waiting to happen in the dark. Budget roughly $150–$250 for the core kit — phone mount, real lock, light set, mirror — and every one of these earns its place within the first month.
Phone holders: navigation without the pocket fumble
Glancing at a mounted phone at 20 mph beats fishing one out of a pocket at 20 mph. Two approaches: the proprietary system (Quad Lock — rock-solid, needs their case) or the universal clamp (fits any phone, slightly bulkier).
Quad Lock Out Front Mount — $39.99. The gold standard for a reason: a patented twist-and-lock that genuinely does not let go, positioned over the stem where navigation sits in your sightline. CNC aluminium arm, out-front design. Watch out: this is the mount only — you need a Quad Lock case or their universal adapter for your phone, sold separately. If you're already in the Quad Lock ecosystem, this is the one. If not, factor the case cost in.
GUB PRO-3 Phone Mount — $25.00. The universal pick: a handlebar/stem clamp that fits nearly any phone with no proprietary case required. The budget route that still holds. Watch out: universal clamps grip with silicone and pressure rather than a mechanical lock — fine for commuting, but check the tightness monthly and don't expect Quad Lock levels of bombproof.
What to look out for: vibration. Ebike handlebars transmit constant buzz that can damage phone camera stabilization over time. Damped mounts exist for a reason — if you ride daily with an expensive phone, vibration damping is worth paying for. Also check your handlebar diameter (usually 22.2mm or 31.8mm at the clamp area) before ordering.
Locks: buy for the bike you own, not the bike you wish thieves ignored
An ebike is a high-value theft target that screams "expensive" from across the street. Cable locks are decoration. You want hardened steel — a U-lock or a folding link lock — from a brand with a real security rating.
Kryptonite New-U KryptoLok Standard — $74.95. The sweet spot in Kryptonite's lineup: hardened shackle, New-U generation design, meaningful theft deterrence without the weight and price of the max-security New York line. This is the minimum a responsible ebike owner parks with outside. Watch out: even good U-locks are heavy (3–4 lbs) and only as good as what you lock to — always through the frame to a fixed object, in a busy, well-lit spot.
Seatylock Foldylock Forever — $135.00. The premium pick: a folding-link design that rides in a compact frame mount instead of swinging from your handlebars, ART 3-star certified — unusually high for a folding lock. Watch out: you're paying for the form factor and certification. If you don't mind a U-lock's weight, the KryptoLok protects nearly as well for less.
What to look out for: lock ratings (ART, Sold Secure) are the only objective measure — marketing words like "heavy duty" mean nothing. And no lock is unbeatable; the goal is making your bike harder to steal than the one next to it. For overnight or all-day parking, two locks (U-lock + chain through the wheels) is the pro move.
Lights: the cheapest safety upgrade there is
A front white light and red rear light are legally required after dark in most places, and daytime running flash makes you visible to drivers who aren't looking for bikes. USB-rechargeable sets have made this a solved problem — never buy disposable-battery lights again.
Cygolite Dice HL 150 / TL 50 Combo — $51.95. 150-lumen front, 50-lumen rear, USB rechargeable, 8 modes with day/night adaptive flash. The Versatite mount fits most handlebars. Plenty for city commuting. Watch out: 150 lumens is a "be seen" light, not a "see the road" light — fine on lit streets, not enough for unlit paths at speed.
NiteRider Swift 450 / Vmax+ 180 Combo — $64.99. The step up: 450-lumen front that actually illuminates dark pavement, 180-lumen rear, USB rechargeable with a low-battery indicator. Watch out: brighter means shorter runtimes on high — know your mode runtimes before a long night ride, and recharge after every ride until it's habit.
What to look out for: mounts. Cheap light mounts slip and rotate on rough roads — check the clamp tightness before every night ride. And "waterproof" on budget lights usually means "survives drizzle"; if you ride in real rain, check the IP rating.
Mirrors: see traffic without the shoulder check wobble
At ebike speeds, a shoulder check means a handlebar wobble at exactly the wrong moment. A bar-end mirror gives you constant rear awareness for the price of a pizza.
Hafny HF-MR083 Bar End Mirror — $19.99. 62mm unbreakable stainless-steel lens, mounts left or right, above or below the bar, fits 14.8–23mm handlebar diameters. The safe default pick. Watch out: bar-end mirrors need open bar ends — if your grips have closed ends or bar-end shifters, check compatibility.
MEACHOW ME-022LS Bar End Mirror — $18.98. Automotive-grade glass lens with anti-glare and anti-scratch coating, larger 5.3×2.5-inch hexagonal head for a wider view. Watch out: it's a single left-side mirror sized for flat handlebars with 17–21mm inner diameter — measure before ordering, and note it's left-side only.
What to look out for: vibration blur. Cheap mirrors vibrate into uselessness at speed; both picks above are known for staying readable. Tighten the mounting bolt properly on install — a mirror that slowly rotates downward is worse than no mirror.
The full kit, budgeted
Adding it up with the value picks: GUB mount ($25) + KryptoLok ($75) + Cygolite set ($52) + Hafny mirror ($20) ≈ $172. The premium route (Quad Lock + Foldylock + NiteRider + MEACHOW) lands around $260. Either way, it's the best money you'll spend on the bike — every item here prevents a specific bad day.

Frequently asked questions
Do I really need a mirror on an ebike?
Not legally in most places, but practically yes. At 20–28 mph you're sharing lanes with cars, and constant rear awareness without wobbling is a genuine safety upgrade for under $20.
Is a $75 lock really better than a $25 cable?
Enormously. Cable locks fall to hand tools in seconds. A hardened U-lock needs power tools and time — most thieves move on to easier targets.
Can I use my regular bike lights on an ebike?
Yes — lights are speed-agnostic. But consider brighter than you think you need; ebike speeds mean you cover ground faster and drivers misjudge your approach speed.
