Veratomic has an easy solution with Quick-Lock, locking quick-releases for bikes.
You can ditch the heavy cables and U-locks with this lightweight yet durable solution. Each Quick-Lock set, priced about $45, includes front, rear and seat post quick release locking skewers plus seat post adaptor.
It's pretty easy to install, and one pull of the specially keyed handle allows riders to secure wheels and seats. The device is a universal replacement quick release that fits most 5mm axels including mountain, road and recumbent bikes. A unique clipping mechanism holds the keyed hand tight, even over rough roads.
In addition to buying the product at bicycle retail shops, you can go to www.myquicklock.com, or enter www.veratomic.com and click through to purchase. For more information, visit the Veratomic Web site or call (877) 778-8707.
