According to the American "Linkage" magazine, although the bicycle is almost perfect in design, the designer does not seem to stop. Some of their work is considered a real improvement, such as the pedals from the Penny Farthing (front and rear small bicycles) pedals to the front wheels, and the improvements made to the rear-wheel-driver rods or chains. However, there are more "crazy" designs than this.
Wheel bicycle
Square wheel bicycle
The bicycle in the photo may seem absurd. Its wheels are actually square. In fact, a square wheel bicycle is also rideable, but the condition is to lay a dedicated "track" for the arc.
2. Pilen concept bike
Pilen Concept Bike
The reason why this bicycle is on the list is due to its cool appearance. The Pilen concept bike was designed by Eric Therner for the Swiss company Pilen Bikes. This design was based on the Le Mans racing car of the 1930s. From the appearance, Pilen gives people a nostalgic feeling, but behind this nostalgic, there are many high-tech equipment hidden - the frame is equipped with LED lights, the seat is composed of two parts, each part Can play a shock absorption effect. Strangely, despite having two brake levers, Pilen didn't seem to have a front brake. In addition, the non-adjustable seat height is also a problem that has to be considered. However, as long as it looks good, who would care about these things?
3. Cube City Street Concept Bicycle
Cube City Street Concept Bicycle
The bike and the inner tube of this concept bike use carbon fiber material and can be folded. The folded head is similar to a backpack, but you still have to find the place where the wheels are stored. If you can do this, you have an anti-theft bike. With a lock, the weight of this bike may increase by a factor of two.
4. Cardboard bike
Cardboard bike
Cardboard bicycles with anti-theft features were designed by student Phil Bridge. The reason why it has anti-theft function is because, who would steal a cardboard bike? Even if it's really lost, it's not a big deal, because cardboard bikes are priced at a negligible amount of $30. The reader should be reminded that this bicycle is not made of scrap cardboard, but uses hexacomb cardboard, a hard material for the packaging industry that can be waterproof after adding foil.
Bridge said that under normal use conditions, the life of this bicycle is about 6 months, and non-paperboard components can be reused. What makes us curious is that cardboard bikes do not have the “big weight that life can't afford.†It must be noted that in the hands of many grumpy people, bicycles made of metal materials cannot escape the fate of being fragmented.
5. Puma bike
Puma bike
This Puma is not a true concept bike, because consumers can buy it on the market, but its weird and amazing degree can definitely be compared with any concept car. Puma is a single gear drive folding dual disc brakes bike. Its biggest highlight is the replacement of part of the frame with the wire rope (lower tube), so that it has quite a good anti-theft feature. The specific approach is to remove the wire rope to act as a lock. Even if the thief cuts the wire rope, it cannot ride the bicycle. However, due to replacing some of the frames with wire ropes, we inevitably have concerns about stability during cycling. Puma bikes sell for up to 1,100 euros ($1,700)
6. The Ride
The Ride
The Ride by Ellsworth Bicycle is another concept car that is available on the market. If you are a person with a lot of money, you may wish to ride this crazy home. The Ride uses a continuously variable transmission that produces a continuous speed ratio, resulting in a stable speed change. If you dial the dial on the handlebar, the angle between the two steel plates on the axle will change, and then adjust the torque. This design was first conceived by Leonardo da Vinci in the 1590s. The Ride sells for as much as $3,000.
