Chilean students invented the "never lost" bicycle body as a lock

The theft of a bicycle is a horrible thing, and it brings a lot of life to life. Now, three Chilean engineering students say they have invented the world's first "never lost" bicycle.

The bicycle abandons the design idea of ​​the traditional external car lock, introduces the bolt concept into the bicycle design, makes the frame form the pin hole, and the seat becomes the movable bar. The two are interlocked and locked, and the lock process is easily completed, and the avoidance is also avoided. The car was stolen, because you want to steal the car, you must first break the frame. As a bicycle family, are you looking forward to this bicycle?

It is reported that this bicycle is called "Yerka", by Juan José Monsalve, an engineering design graduate from Adolfo Ibanez University in Chile, and Christopher. · Cristóbal Cabello was co-developed with Andrés Roi.

The Yerka bike will be available early next year and will be priced between $400 and $1,000 (approximately RMB 2452 to $6129).

Composite Drainage Net


HDPE Three dimensional composites drainage net is a new type of drainage geotextile material. It is one three-dimension geonet composited with two needle-punched non-woven geotextiles. Three dimensional composites drainage network consists of a tri-dimension thick vertical rib, and a inclined rip on the top and bottom. Double sided adhesive seepage geotextiles form a"filtration - drainage - ventilation - ." overall performance, and can replace the traditional sand and gravel.wildly used in erosion control, foundation wall drainage, landfill leakage collection, leakage detection, methane gas collection,pond leak detection, roadway and pavement drainage and other subsurface drainage system applications.
