Masterlock Street Cuff Sport Lock

BikeRadar verdict

4 out of 5 stars

"Tough, and one we would recommend as a quick-stop lock"

By Warren Rossiter, Cycling Plus

The Street Cuff is essentially a pair of handcuffs – you can wrap one cuff around a frame tube, the other to whatever you're locking it to.

Because the cuffs are always filled, they're impossible to lever open; it’s also difficult to cut or hammer them and the central chain rotates freely. We couldn’t lever the lock, we struggled with the domed rivets and after five minutes had inflicted only cosmetic damage. 

Overall the Cuff is ideal for quick stops. It’s not ideal for higher security needs, as the design means you can’t use it to lock anything but the frame – leaving the wheels, seatpost and saddle vulnerable. It passed our general manual attack, and took 33.5 seconds to cut with our portable angle grinder.

    "Masterlock's funky Streetcuff design has been around for a couple of years and the design has been tweaked and improved strength-wise in that time."

    *How old is this review? I bought my cuff lock back in 2002 (it's now 2007), which is more than "...a couple of years."

    It sounds as though you reviewed the single-link version... I use the 9-link version with a Bianchi Milano and have no problem routing the lock through the front wheel from the downtube --> the bike rack.

    Severing the cuff section in >35 seconds... what did you use to accomplish this? It's genuinely difficult for me to imagine what non-power tool you could use to cut through the steel cuff. The language of the review seems deliberately ambiguous on this point.

    I've owned a cuff lock since the summer of 2002... so it ought to be one of the earlier, more vulnerable versions according to this.

    I've used my bike to commute to and from a local state university campus for the past few years, where there are a fair number of bike thefts. I'm graduating in the spring and my bike has been locked with the cuff lock on campus at least 4 days a week; generally from 10am - 7pm. Sometimes, I see the remains of someone else's bike that has been stolen... but my Milano is always right where I left it. While I am able to pick the cylinder lock on an older u-lock with the inards of a bic pen, I cannot similarly pick the cylinder on a cuff lock. While there are videos of people able to do this with the older u-locks, I've yet to see this done with a cuff lock.

    In short, I've been very pleased with the cuff lock. As an alternative to a u-lock, it is lighter, easier to use and from my experience, reliable. I don't care for the keys... they do wear out... I've had them replaced free of charge twice so far. So to be fair, I'd have to give them 4 stars out of five for this reason.

    I have used these for a number of years as they have a big advantage for recumbents and other bikes which are non-standard frames and do not have a "triangle in the frame..

    These are the exact size to secure around a 50 mm recumbent frame - it also works well with the Birdy Airnimal and Brompton

    you need to be very careful when using keys, my brother lost his car key once and had to do a lot of rushing, its always better to have a fixed locksmith, like Fort Worth locksmith for me
