Bike Size Charts

BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews

We have read all expert and user reviews on the ABUS CityChain 1010. In summary, this is what cyclists think.

6 reasons to buy

  • Testers demonstrated that the CityChain 1010’s 9mm thick hardened steel chain can hold up for minutes against attacks using aggressive tools, in real-world conditions.
  • Like all chain locks, the CityChain 1010 provides flexibility in locking situations and portability.
  • The CityChain 1010 comes in four different lengths:
    • 85cm (34”)
    • 110cm (43”)
    • 140cm (55”)
    • 170cm (67”)
  • Experts and users like that the CityChain 1010 has a fabric sleeve to provide protection for bike frames and components.
  • ABUS’ Plus lock cylinder protects against manipulations such as picking.
  • The CityChain 1010 received a ‘Gold’ rating (for high theft-resistance) from the security certification body Sold Secure. It has also been approved by ART.

3 reasons not to buy

  • Other bike locks weighing slightly more than the CityChain 1010 will hold up to significantly more abuse from thieves.
  • The CityChain is susceptible to attack by sledgehammer, angle grinder or bolt cutters.
  • With weights varying from 4.08 lb to 7.05 lb, some experts and users found this lock to be on the cusp of being too heavy to carry around as a cyclist.

Bottom line

The CityChain 1010 is a reasonable and respected choice for an upper-tier bike lock. While it doesn’t offer the same security and light weight as a U-lock, it’s much easier to find a place to lock your bike. Ranging from four to seven pounds, the weight may be an issue for some riders and commuters. However, for e-bikers, the CityChain 1010 might just be a great choice. For even higher security (but also more weight), you might look to ABUS’ own ‘Granit CityChain XPlus’ range.

For those looking for the most flexible, most portable answer to high-level bike security, then the super heavy duty CityChain 1010 is definitely one of the best. It weighs a ton.

Abus Bordo, GRANIT Plus and CityChain Unboxing:
Locks for Lockdown Special!

You’ve got 9mm hex-section hardened links, full fabric cover. It’s heavy. This chain gives you a bit more flexibility in what you can lock to and how you can carry it and it’s really hard to burst. Ideally, you want a D-lock and you want a CityChain like this.

Tested: ABUS CityChain 1010 Review

The weakness of the CityChain 1010’s lock body when attacked with a sledge hammer means it’s very important to keep it off the ground, though we strongly recommend this with all locks.
