Zovii Alarm Grip Lock review | Motorcycle lever lock tested

Date reviewed: January 2025 | Tested by: John Milbank | RRP: £25.99 | Weight: 257g | www.sportsbikeshop.co.uk

The Zovii Alarm Grip Lock on review here is admittedly one of the more basic security devices, but it is a useful deterrent, it’s got a loud alarm built in, and it’s easy to use, which means it’s more likely to be something you fit when you’re out with the bike…

Pros & Cons

Size and weight

Weighing just 257g with the supplied CR2 battery fitted, this Zovii lever lock is very easy to carry about. I wouldn’t suggest putting it in a pocket, in case you fall on it, but it isn’t bulky at all.

The 120db alarm is armed as the lock barrel is pushed in, when it beeps once. If there’s movement it will chirp five times before sounding the siren. It disarms with two beeps the next time the barrel is pushed in.

Made of tough plastic, the Zovii Alarm Grip Lock simply fits over the right-hand bar and clamps shut with the brake lever pulled back, preventing the bike being easily pushed away. The lever slot is adjustable through four positions by loosening a Philips-head (not Pozidrive) screw, so you can set it up to ensure the brake is properly applied. The box says you can also use it to lock the clutch lever, but that’s not going to stop a thief pushing the bike away, so stick with the brake.

If your bike has handguards, you probably can’t use a lever lock

Note that if your bike has handguards fitted, this almost certainly won’t work – I couldn’t get it on my 2019 R1250GS or the Zontes ZT350, but it was fine on my 1999 ZX-6R and 2001 VFR800.

Zovii (which is sold exclusively in the UK by Sportsbikeshop) claims the battery will last eight to 12 months with normal use, but that it could be less. Replacements are cheap and easy to find though, costing as little as £1.59 from Battery Station.

I haven’t been able to test the battery life, but I did leave it outside for a month over Christmas in heavy rain and freezing temperatures; it continued to work flawlessly.

Three keys are supplied.

Resistance to attack: lock picking

While click-hungry YouTubers will try to make lock-picking look easy (especially when they’re hawking their own tools), it’s simply not a theft method seen on UK streets. Most thieves don’t have the time, patience, tools or skill to pick locks, and rely instead on brute force or angle-grinders.

Resistance to attack: drill

<h2 class="headline-6">Resistance to attack: drill</h2>

Thanks to a tough, free-spinning cover plate, the Zovii’s barrel is very hard to drill out – after trying with two drill bits, I was unable to defeat it.

Resistance to attack: hammer

A hammer attack is fairly ineffective against a lever lock like this Zovvi, but striking the end could see the lever itself snap, which will then allow the bike to be pushed away.

Pry attacks are also more likely to be against the brake lever than the lock itself.

Resistance to attack: angle-grinder

Cutting the plastic body of the Zovii is, unsurprisingly, quick and easy, with no sparks or much noise beyond the tool itself.

Zovii Alarm Grip Lock review: Verdict

The Zovii Alarm Grip Lock is not a high-security device, but it is much better than using nothing. It’s convenient and very cheap, plus if you pair it with other locks it makes the bike even less attractive to a thief.

The ear-piercing siren is painful in an enclosed space and attracts attention outside, again making your bike less tempting than the one that’s next to it and isn’t locked.

There are several ways to defeat a lever lock, but that doesn’t make them useless.
