## Overview

The InterLock Crosstown Post Bicycle Lock is a revolutionary bike lock that seamlessly integrates into your bike's seat post, providing unmatched convenience and security. With a weather-resistant design and dual key access, this award-winning lock is perfect for the modern cyclist who values both style and functionality.

## Description

The InterLock Crosstown is the most innovative and convenient bike lock in the world. This product seeks to solve a problem - the annoyance of carrying bike locks. The InterLock is a Seatpost and a Bike lock in one. To install, all you need to do is replace your seatpost. The lock is fully integrated and is not removable from the seatpost. This means even if someone removed the seatpost from the bike as long as you have wrapped the cable through your frame your seat can not be stolen. The high tensile wrapped steel cables are 36 inches (90 cm) in total length and the product weight is 1.5 lbs (620 grams) including lock and seatpost. The seatpost is 3D Forged, 6061 Aluminium and has a diameter of 27.2mm. The InterLock won a GOLD award at the Taipei Cycle Show 2014! Arranged by iF Design, only 5 Gold awards are given away each year. The Taipei Cycle Show has over 3300 exhibitors, so the award is a big deal! We're stoked! The Interlock was also awarded a Eurobike Award in Germany in 2014!!! Remember - the InterLock is a medium-security device with convenience as it's strong suit, so if you live in a high risk area for bike theft, we recommend using the InterLock in conjunction with a U-Lock for the ultimate security solution. Use a U-Lock or D-Lock to secure the front wheel and frame while using The InterLock to secure the Seat/Seatpost/Rear Wheel .

## Features

- Easy to install by just replacing your old seat post with the InterLock
- Awarded a 2014 Design Innovation Gold Award at the Taipei Bike Show

    Excellect execution of a clever idea for built in security
  

*by M***. on Reviewed in the United States on March 30, 2015*

First off I have to say I had tinkered with the idea for something like this about two years ago after having my entire seat and attached post stolen. I got as far as cutting a cable lock in half and spot welding the ends together, then inserting them into a drilled out seat tube, It was never anything I imagined producing for sale.  I sure wish i had followed through with producing it, because (aside from making some $$$ off the idea) this is truly a great concept finally realized, and much cleaner then anything you can make on your own!I bought this after purchasing my Trek DS 8.5.  With my past experiences in theft, i wanted to invest in something more than a beefy U-lock.  I already have locking skewers for the wheels, but the quick snatch and grab thefts are what ive had issues with in the past, and like i said, and I wanted to limit the amount of gear i would have to carry on my commute every day.  In browsing around, i came across the Interlock website and just had to give it a try, since it was so reminiscent of a past project of mine.  It really does work flawlessly, and looks great, especially if you have a matte finish bike like mine.The cable cleanly stores away so all i have to carry with is my U-lock and key for total protection.  I typically have a Kryptonite Evo lock that is used to secure the front wheel and/or frame to an anchor, and the Interlock I will use pulled downward to link the seat post to the frame and rear wheel.  It is advertised as being usable as a primary lock which a shackle is not usable, though personally i would not rely on this as your only lock due to the cable being on the thin side.  Like you're always told, if someone really wants to steal something, all you can do is make more deterrents, and even Interlock recommends using this in conjunction with other locks if in a high theft area.The 27mm version fits my Trek perfectly without shims, though as you can see from the picture i posted, it will not fully retract into the post as in the advertisement.  I have a X-large 22.5" frame and was surprised to see this with the long seat tube on my bike, though Trek's are known for having a sharp drop on their headtubes, so i would not hold this against the product, as im sure most bikes would not have this issue.  The only thing i would suggest is a thicker cable on the next revision (though again, it is not meant to be your primary lock).  Otherwise its a great product, with great execution of an idea, and im glad to have it on my new bike.

    Very convenient way to lock up my bike for short-term parking
  

*by R***. on Reviewed in the United States on August 6, 2015*

Very nice way to temporarily lock up my Electra Townie. I use this only to run in a store, not for long-term parking, since the cable is not tremendously thick. Very convenient, and it's always with my bike, so I have no excuse not to lock it up. For long term, I've got a U-lock,I've very pleased with this purchase.

Great invention. I gave it 4 stars because the lower cables plastic coating gets sliced when retracted by a sharp edge.
