Monimoto alternatives: how to choose a self-fit tracker

Monimoto set the template for this category, and it earned that. If you are looking at alternatives, these are the six things worth comparing — and we will show you where we lose.

Last updated 2026-08-24 · Written by the Sentrix team, Britain

There is a whole category of vehicle tracker that barely existed ten years ago: self-fit, battery powered, and paired to a key fob. You hide it yourself, it sleeps until something moves, and it rings your phone rather than a control room. Monimoto made this category popular in the UK, and most people searching for an alternative are searching for one of three reasons: the running cost, the size, or simply wanting to see what else exists before spending money.

We build one of these things, so treat this page accordingly. What we can do is be accurate about the numbers and clear about which parts of the comparison we lose.

First: is this the right category for you?

Self-fit trackers are one of three options, and the wrong one for some people. If your insurer requires a Thatcham S5 or S7 device, nothing in this category qualifies — not Monimoto, not us, not any battery tracker you hide yourself. That is not a marketing distinction, it is structural: approval requires professional installation and a monitoring centre. We cover what the categories mean in Thatcham S5 vs S7 explained.

If your policy does not require approval, read on.

The six things worth comparing

1. Total cost over three years, not the sticker price

Every GPS tracker needs a SIM, and the yearly airtime is where the money actually goes. A device that is £20 cheaper with a subscription £10 a year dearer costs you more by year three. Do the arithmetic for the period you expect to keep the vehicle.

2. How honest the battery claim is

Standby figures are the most stretched number in this market. What matters is the conditions: how often it woke up, whether it had signal, at what temperature. Ask any manufacturer — and treat a confident figure with no conditions attached with the same suspicion as no figure at all.

3. Physical size, because it decides the hiding places

The difference between a matchbox and a paperback is the difference between a frame cavity and under the seat, and under the seat is the first place anyone looks. Size is not a spec-sheet detail here; it is most of the product. See where to hide a tracker.

4. What happens after the first alert

This is the question almost nobody asks. A device that keeps transmitting can be found with cheap detection kit once the vehicle is somewhere quiet. Ask what the device does in the minutes after it has raised the alarm.

5. How the alert reaches you at 3am

A push notification you sleep through is worth nothing. A phone call is much harder to ignore. Whatever the mechanism, test it on your own phone, at night, with your real do-not-disturb settings.

6. Whether it survives indoors

Stolen vehicles end up in vans, lock-ups and underground car parks, where GPS cannot reach. Ask whether the tracker falls back to mobile-network positioning. It is far less precise, but a rough area beats silence.

The published numbers

Only figures each company publishes, with sources at the bottom. Prices change — check before you buy.

Where we lose, plainly

Monimoto has years of independent reviews in the UK motorcycle press and a published battery figure. We have neither — we are new, and we are not going to print a standby number before our own bench tests are finished. If a proven track record is what you are buying, that is a real argument for buying theirs.

Where Sentrix is different

Two things, and only two worth claiming:

Beyond that: 40 × 40 × 60 mm, no wiring, about five minutes to fit, and it moves to your next vehicle. It works on motorbikes, vans and cars.

What none of them do

No tracker in this category recovers your vehicle. The police do that, and only after somebody rings them. A self-fit tracker buys you one thing — finding out early — and everything after that depends on what you do next. Worth reading before you need it: what to do in the first hour.

How to decide

  1. Check your policy first. If it requires S5, the whole category is out and you have saved yourself the research.
  2. Work out three-year cost, device plus airtime, for each option.
  3. Measure your hiding place before you buy, not after. Take the tape to the bike.
  4. Decide what you value more: a proven product with years of reviews, or a lower running cost and a device that goes quiet after the alert.
  5. Test whatever you buy in the first week, while you can still return it.

Sentrix

Hidden tracker that knows your key, for motorbikes, vans and cars. The app is free; live tracking needs a SIM, so after two free months it is £30 a year. Free UK shipping, 30-day returns, one-year warranty.

30 days to send it back. We would rather you tested it properly than kept one that was not right.

Common questions

Is there a self-fit tracker with no subscription at all?

Not a GPS one. Live tracking needs a SIM and SIMs cost money, so a product advertising no ongoing cost is either building it into a higher purchase price or is a Bluetooth tag rather than a tracker. Bluetooth tags only report when someone else’s phone passes near them, which is no use in a lock-up.

Why would I want an alternative to Monimoto?

The common reasons are running cost, physical size for a particular hiding place, or wanting a device that stops transmitting after it has alerted you. If none of those apply to you, there is nothing wrong with buying the well-reviewed option.

Can I move a self-fit tracker to a new bike?

Yes — that is one of the real advantages over a wired, professionally fitted unit. There is nothing to uninstall and nothing tied to the vehicle’s electrics.

Do any self-fit key-fob trackers have Thatcham approval?

Not in this category, because approval requires approved installation and a monitoring centre. If your insurer requires S5 or S7 you need a wired, monitored device, whatever else you like about the self-fit ones.
