In the Innovation Engineering programme at UWCSEA East, High School students learn that a first draft is never the final product. By blending science, mathematics, and applied design, the curriculum teaches students to tackle complex challenges through iterative problem-solving, prototyping, and testing. They learn to analyse systems, build physical models, and discover how small refinements can completely change an outcome. Grade 10 student Ayaan shares how these principles helped his team turn a mechanical setback into a winning comeback at UWCSEA's annual pedal kart challenge, part of the Activities programme.
From Pedals to Precision: Engineering a Comeback
One of the most exciting traditions at UWCSEA is the annual pedal kart race between UWCSEA Dover and East. At first glance, it looks like simple teams racing human-powered karts around a track that winds through the school grounds. But behind the race itself lie months of experimentation, mechanical problem-solving, and teamwork.
Although the competition is not formally part of the school’s Innovation Engineering programme, the same mindset design, iteration, and problem-solving drives everything we do when preparing our karts. Teams take a pre-built kart and push it further: improving performance through creative engineering ideas, testing different mechanical setups, and learning how small changes can transform the machine.
My own journey with the pedal kart race began in Grade 8.
That year, my role was simple: I was a driver. I remember sitting low in the kart at the Dover Campus, nervous but excited for the three-hour endurance race. At the time, Dover’s team seemed unstoppable. Lap after lap they surged ahead while our East team struggled to keep up. By the end of the race they had nearly doubled the distance we covered.
For me, that loss left a deep impression. Watching the other team glide past us again and again made me realise something important: raw effort alone wasn’t enough. Engineering mattered. Aerodynamics mattered. Drag mattered. The race wasn’t just about who pedalled harder—it was about who built the smarter machine. Instead of discouraging me, that defeat made me hungry.
By Grade 9, my role had changed completely. Alongside my peer Arham, I became one of the two leaders responsible for developing our team’s karts. On race day, around ten students represented the East Campus with two karts, but the work behind the scenes required much more than just showing up and racing.
As project leaders, Arham and I coordinated the entire process. We managed the engineering work, testing schedules, design decisions, and race strategy. One of the most important lessons I learned during this time was how to organise a team effectively. Instead of assigning tasks randomly, we began identifying what each person was best at, who had mechanical skills, who paid attention to detail, who could think strategically and distributed responsibilities accordingly.
Whenever disagreements arose, we didn’t rush decisions. Instead, we discussed the pros and cons as a group, analysing how each idea would affect the kart’s performance. That collaborative approach helped us refine our designs while ensuring everyone remained invested in the project.
The technical side of the work became the heart of the experience. Because the kart itself was pre-built, our challenge was to improve it. We experimented with different setups, modifying gear ratios, optimising weight distribution, improving steering behaviour, and adjusting driver ergonomics so power could be transferred more efficiently through the pedals. Each change was small on its own, but together they transformed how the kart behaved on the track.
However, it was not always smooth sailing. One of the biggest engineering challenges we faced was when we discovered that our wheel hubs were damaged. The spokes had bent the original hubs out of shape, which meant they could no longer fit properly onto the kart. But we didn't give up hope, as we decided to redesign the solution ourselves.
Using a rotary tool (Dremel), we carefully machined the hub down to a precise size so it would fit perfectly with our axle. It was delicate work—remove too much material and the hub would be ruined—but after several attempts, we produced a custom-fit component that worked better than the original. That wheel modification remains one of the innovations I’m most proud of because it forced us to solve a real mechanical problem through creativity and persistence.
By the time race day arrived, all of that preparation came together.
This year, the race took place around the East Campus grounds on a course roughly one kilometre long. Each Campus fielded two karts, and teams rotated drivers every two to three laps to maintain endurance. Because our kart had a relatively low gear ratio, making it harder to accelerate from a standstill, we developed a strategy to minimise time lost in the pit. As soon as a driver swapped out, teammates would push the kart forward to help it regain speed instantly before the next driver began pedalling.
It was a small tactical detail, but it saved valuable seconds every time we stopped.
During the race itself, the energy was intense. Drivers rotated in and out, mechanics monitored the kart, and teammates stayed ready to jump in whenever needed. Lap after lap we pushed harder, testing both our engineering and our endurance.
The moment we knew the race had turned in our favour came when we lapped the other team and then continued to pull further ahead. With each lap we completed, we could visibly see the gap widening between us and our competitors, which raised the confidence of the whole team. Finally, crossing the finish line wasn’t just a victory; it was proof that the months of work had paid off. The loss from Grade 8 had transformed into something much more meaningful: a comeback built through engineering, teamwork, and determination.
Beyond the race results, the experience shaped how I think about innovation. I learned that even the smallest modification can influence multiple systems in a machine. Changing a gear ratio can affect acceleration. Adjusting weight distribution can influence handling. Engineering isn’t about one big idea, it's about understanding how many small ideas interact.
Leading the team also taught me something about myself. Early on, I made the mistake of trying to manage too much personally instead of delegating work to others. Over time I realised that the best teams succeed when everyone contributes their strengths. Leadership, I discovered, is not about doing everything, it's about enabling others to do their best work.
Today, as I prepare for the next race in Grade 10, I carry those lessons forward. While my team and I are eager to further build and develop our kart, our focus remains the same: pushing the kart further through creative and unexpected ideas.
The challenge may also grow larger. A third school in Singapore, the German European School Singapore (GESS), may join the competition with their own kart. If they do, the race will become even more competitive.
But that only makes the goal clearer.
We plan to return to the track with bold engineering ideas, a stronger team, and the same hunger that began after my very first loss. And when the race begins, we’ll be ready pedalling not just for speed, but for the innovation behind it.
Our aim is simple: to win again, and to prove that great engineering can turn even the toughest defeat into the start of something better.
