How to fix the single-speed bike you hate
Posted February 08, 2018 12:17:14 Bike modifications, including single-spd bike modifications, can save you money and time, but there’s a downside.
They also may increase your chances of injury or death.
A new study from researchers at the University of North Carolina, Chapel Hill, and the University at Buffalo has found that a single-drive system, with a bike with no gears or brakes, may increase the likelihood of injuries.
The study, published online in the journal Injury Prevention, examined the injuries suffered by people riding in single-wheelers in four U.S. cities: Raleigh, N.C.; Buffalo, N., New York City; and San Francisco, Calif.
Participants who used a single speed bike were asked to ride in a designated lane for the duration of the study.
Then, they were asked what they thought would happen if the vehicle traveling at the speed of the single speed had a sudden stop.
They were asked if they would consider going back to their original speed, which was twice the speed they would have had if they were riding a two-speed vehicle.
They weren’t asked to predict what would happen when they were given a second opportunity to get around the traffic.
After the second opportunity, they completed an evaluation task.
They had to choose one of three responses: the bike had no gears and brakes, a single gear and a brake, or the bike did have gears and pedals.
The results showed that the most common single-gear and single-pedal systems resulted in injuries, with both systems being the most dangerous for the most people.
“The main thing that is missing in most bike modifications is the ability to control the bike’s power and torque,” said study author Jennifer K. Clark, a professor in the Department of Mechanical Engineering and Applied Science.
“There are only two types of controls that we know about: the gear and the pedal.
These two systems are usually not the same.
For most people, we don’t really know what the difference is between a gear and an electric pedal.”
The study also found that, for people riding single-wheeled vehicles, the majority of injuries were from falls.
The most common injuries were sprains and strains, such as lacerations, bruises and cuts, according to the researchers.
They estimated that single-piston bike modifications cost between $5,000 and $8,000, with the cost of gear changing at least twice as much.
“This research is really about how to get better at managing injuries,” Clark said.
“You can make a single wheeler safer by adding more gears, but you can also make it more dangerous by changing the power.”
Kari H. M. Smith, a research associate in the department of mechanical engineering and applied science at UNC-Chapel Hill and the study’s senior author, said the findings highlight a need to improve the designs of single-stroke bike systems.
“People don’t want to get hurt,” Smith said.
For instance, the study showed that people who rode single-speeds were significantly more likely to fall when riding in lanes of traffic.
“For me, it was a real relief to have this study to look at,” Smith added.
“I’m happy to see there are so many people who want to do something with their lives that can help improve the health and safety of cyclists.”
