Best Bike Locks Under $25 for Adult Tricycles
At this tier a lock is a deterrent for short stops, so choose length and handling first and treat security as a bonus.
Updated · 4 min read · 4 products evaluated
An adult trike is awkward to lock. It is long, the rear axle is wide, and the frame has fewer clean tubes to loop through than a diamond-frame bike. A short, stiff lock that works on a commuter bike can fail to reach a post and a wheel at once on a trike. Length matters more here than almost anywhere else.
Low-cost locks are honest about their job: they stop a casual walk-off, not a thief with a cutter. Thin cable is quick to snip, and light chain only buys a little more time. This guide ranks the budget locks that make sense for a short errand stop, and explains when to step up to the full pillar guides for U-locks and heavy chain.
Short answer
The Master Lock 8122D is the pick for most trike owners because its 6 ft reach and resettable combination handle a wide rear axle. The Amazon Basics 70 inch cable matches it on reach with keys instead of dials. The GRIFEMA 4 ft chain is the only choice here with real links, and the Jokmae 32 inch coil suits a quick bag-and-basket stop only.

Best Overall1 of 4
Master Lock 8122D 6 ft Cable Lock
The longest reach and a resettable combination make it the most practical cheap lock for a wide trike.
Best for
Short errand stops
Why we like it
The 8122D uses a braided steel cable that is half an inch thick with a vinyl coating, and a four-digit combination you set yourself. Six feet of cable is the useful number on a trike: it can loop the frame and the rear wheel and still reach a rack or post, which a short lock often cannot.
Next to the Jokmae it is far longer and thicker, and next to the Amazon Basics it swaps keys for a combination you can reset if you forget it. It is still a cable, so it deters a casual grab rather than a determined thief. Pair it with a second lock for anything left for more than a few minutes.

Best Keyed Cable2 of 4
Amazon Basics 70 in Cable Lock
A long, simple keyed cable for riders who prefer a key to remembering digits.
Best for
Key-preferring riders
Why we like it
This lock is a plain 8mm steel cable, 70 inches long, with a weather-resistant plastic coating, a key cover and two keys. The extra inch or two over a bike-sized cable is what lets it pass through a trike frame and around a post.
Compared with the Master Lock it is thinner and uses keys, which suits riders with stiff fingers who struggle with small dials. It is also one more thing to keep track of. Choose it when you want the same reach as the Master Lock and prefer a key.

Limitations
- 8mm cable is thinner than the Master Lock
- Lost keys mean a cut lock
Consider it if

- Locking to a distant post
Skip it if
- Anyone leaving a trike unattended long
Best Chain Option3 of 4
GRIFEMA 4 ft Hardened Steel Chain Lock
Actual chain links with a nylon sleeve, the closest this tier gets to a real chain.
Best for
A step above cable
Why we like it
The GRIFEMA is a 4 ft chain with 7mm hardened alloy links in a nylon sleeve, and it ships with two keys. A chain resists snipping better than a thin cable because links are harder to bite through with small cutters.
It is shorter than the two cables above, so check that four feet reaches both a frame tube and your rack or pole before relying on it. It is also heavier to carry. It beats the cables on cut resistance but is still a light chain, so treat it as a budget deterrent, not a replacement for the heavy chain in our full chain lock pillar guide.
Key specs
| Size | 4 ft long, 7mm links |
|---|---|
| Features | Nylon sleeve, two keys, hardened alloy |
Specs can change between model years; confirm the exact version before buying.
Strengths
- Links resist small cutters better than cable
- Nylon sleeve protects the frame
- Two keys included
- Can lock more than one bike
Limitations
- Shorter reach than the cables
- Heavier to carry along
Consider it if
- Racks and fences with limited loops
- Riders wanting more cut resistance
Skip it if
- Riders who need a very long reach
Best Compact4 of 4
Jokmae 32 in Combination Cable Lock
A short coil that only suits a quick stop or as a second lock.
Best for
Basket and wheel add-on
Why we like it
The Jokmae is a 10mm braided steel cable, 32 inches long, that coils up and uses a four-digit resettable combination. The cable is thick for its length but there is not much of it.
On a trike, 32 inches is rarely enough to reach a post and the frame together, so it works best to secure a removable basket or a wheel, or as a second lock alongside a longer one. Brands sell it as a basic security measure, and that is the honest framing. It is a compact add-on, not a main lock.
Key specs
| Size | 32 in long, 10mm diameter |
|---|---|
| Features | 4-digit resettable combination, self-coiling |
Specs can change between model years; confirm the exact version before buying.
Strengths
- Thick 10mm cable
- Coils to a small bundle
- Resettable combination
- Light to carry
Limitations
- Too short for most trike frames
- Cable is still easy to cut
Consider it if
- Securing a basket or wheel
- A second lock add-on
Skip it if
- Locking a trike to a post alone

How We Chose These Bike Locks Under $25
- Reach around a wide trike
- A trike needs a longer lock than a diamond-frame bike, so we weighted cable and chain length heavily and checked it against the rear axle.
- Honest security level
- We compared cable thickness and link type and did not assume budget locks stop cutters, which is why every pick is described as a deterrent.
- Ease of use with older hands
- Resettable dials, keyed locks and sleeves were compared for the riders most likely to own a three-wheeler.
- Fit for this tier
- Products that were really scooter holders, disc locks or the wrong item were dropped, leaving only locks that make sense on a trike.
What to Look for in a Bike Lock Under $25
Length and the rear axle
A trike's rear axle is wide and its frame is long, so the lock has to wrap more steel than a normal bike. A lock that is too short forces you to secure only a wheel.
Measure from where you will park to the nearest post, then add the loop around the frame. Aim for at least five feet of cable or chain and check that length on the product title.
Cable versus chain
Cable is flexible and light but is cut quickly with inexpensive tools. Chain links are harder and take longer to defeat.
At this tier a chain such as the GRIFEMA is the best step toward security, but it weighs more. Pick cable for lightness and chain for a bit more resistance.
Key or combination
Keys can be lost and combinations can be forgotten, and either leaves you stuck at a rack.
If you ride with stiff fingers, a keyed lock like the Amazon Basics is easier. If you do not want to carry keys, choose a resettable combination such as the Master Lock and pick digits you will remember.
Use it as part of a pair
A cheap lock buys seconds, not minutes. Using two different locks makes a theft more work and often sends a thief to an easier target.
For overnight or long stops, step up to the heavy locks in our U-lock and chain lock pillar guides, and use these budget locks as the second layer.
How to Choose
By How Long You Leave It
| Situation | Our pick | Why |
|---|---|---|
| Five minutes at a shop | Master Lock 8122D | Long reach and fast dial lock |
| Stop near a distant rack | Amazon Basics 70 in Cable Lock | 70 inches reaches farther and uses keys |
| Busy bike rack, you want more resistance | GRIFEMA 4 ft Chain Lock | Hardened links are harder to snip than cable |
| Securing a basket or wheel only | Jokmae 32 in Cable Lock | Compact coil, light to carry |
Cable vs Chain
- Cable
- Master Lock 8122D, Amazon Basics and Jokmae are cables. They are light and long, but a small cutter goes through them quickly, so they only discourage opportunists.
- Chain
- The GRIFEMA is the only chain here. Links resist cutting longer, but it is shorter and heavier, so confirm four feet reaches your frame and your post.
Most trike owners should start with the Master Lock for reach and add a chain or U-lock if the trike is parked outdoors.
For Apartment and Shared Racks Specifically
- Look for
- A lock that reaches the frame and the rack with slack to spare, and that is easy to operate with cold or stiff hands.
- In this comparison
- The Master Lock 8122D covers both needs. If the rack has few openings, use the GRIFEMA chain, which is easier to thread through tight spots.
When to Spend More
- Spend more if
- You park outside overnight, live in a high-theft area or own an electric trike. Move to the U-lock or heavy chain in our pillar guides and keep the Jokmae as a spare.
- Save if
- You only make short stops with the trike in view. The Master Lock 8122D or the Amazon Basics cable is enough for that.
Frequently Asked Questions
Is a cable lock enough for a trike?
It is enough for a short stop where you can see the trike. A cable can be cut with small tools, so for longer stops or outdoor storage you want a U-lock or heavy chain as well.
Do I need a longer lock for a trike?
Yes. The wide rear axle and long frame mean a lock under four feet often cannot reach a frame tube and a post together. Five to six feet is a more comfortable length.
Combination or key, which is better?
A combination avoids lost keys but can be forgotten, while a key is simple but easy to misplace. Choose the one you are more likely to manage reliably, and keep a spare key somewhere safe.
Can I use two cheap locks instead of one good one?
Two locks help because a thief needs two tools or more time, but two weak locks are still weak. Use them as extra layers rather than a replacement for a strong U-lock.
Where should I lock a trike?
Lock the frame and, if you can, a wheel to a fixed post or rack. Do not lock only a wheel or a removable basket, and avoid leaving the trike where no one passes.
Bottom Line
A lock in this tier is a deterrent, not protection against a prepared thief. The Master Lock 8122D is the best all-round buy for its reach, the GRIFEMA is the step toward real security, and all of them are best paired with a second lock.
