I would like to have a new bike lock system which will be strong, sleek, and long enough to pass through both wheels and secure the bike to a stationary object. The system will consist of a steel, pick resistant lock and a flexible titanium bow that will be able withstand a saw and a 48-inch bolt cutter. The largest size will weigh less than 5oz, which will be one third the weight of a conventional U-lock. The flexible bow will be large enough to wrap around objects as large as 5.5...

I want to have an eco-friendly hybrid bicycle that can be converted into a scooter, thanks to its built-in electric motor and on-board lithium-ion battery. When pedaling such a bike, users will charge the battery. The bike will have a semi-automatic 8-speed transmission, which should help when trying to ride up steep slopes.

If the puncture is very big, take up the inner tube at all and fill in the tire with hay, grass, leaves, etc. With such a tire you can ride 25-30 miles. As you see, both of these advices are for the extreme cases.

You can now use a bicycle to go to the place which seems to be reached only by a tractor. Downhills and parks in winter are full of cyclists who do not want to stop cycling. Some of them buy snow tires; the others use ski-bikes (special bikes with skis instead of wheels). Unfortunately, in the first case grip of wheels with snow is not so good and in the second case there are no pedals which are the main bicycle attribute. A Canadian innovation company suggested a winter kit...
