Zane Middle School pedal desk
The purpose of this ENGR 215 project is to build a desk with an attached pedal and fidget toys on top of the desk for students at Zane Middle School. Since middle school students have tons of energy and sit in a classroom most of the day, pedaling while working on assignments allows them to quietly get their jitters out will getting work done.
Catherine L. Zane Middle School is located in Eureka, Northern California. This 6th-8th grade school focuses their curriculum on STEAM (Science, Technology, Engineering, Art, and Math). Education With Movement’s goal was to create a resource for students to utilize during instruction that allows them to fidget quietly.
Problem statement and criteria
Team EWM’s objective is to construct a desk that allows students to remain focused and on-task during class instruction while also safely fidgeting quietly by having access to a bike pedaling system under their desk.
Table 1: Criteria for Final Design
|Safety||Moveable components should be shielded, table should have a sturdy base.||10|
|Durability||Design will be used daily, so it must be sturdy and not break.||9|
|Sound Level||Must be as quiet as keyboard typing.||7|
|Child Size||Design should be adjustable to account for all students' sizes.||6|
|Transportability||Must be able to move around with ease.||5|
|Movement||Must provide students with adequate movement to allow quiet fidgeting.||5|
|Cost||A maximum budget of $400, but preferably less than $100.||4|
Description of final project
Our final design features an adjustable table with a pedal system. The desk has two main legs with parallel runner boards on the bottom, giving the desk a strong base. It has five preset heights that utilize four nuts and bolts, to hold its position. The pedal system is a recycled bike frame and pedals secured to two boards acting as a base. The table top was created with a piece of plywood on the bottom for strength, then a dry erase board was put on top of that. A ¼" piece of trims runs along the perimeter to keep things from rolling off.
Use a gallery of prototyping photos and lessons learned.
Material and construction costs include any material or labor cost that became a part of our overall total cost of the project. We were lucky enough to be able to use all the tools needed for construction for free which significantly lowered the total cost and allowed us to remain under our budget of $325.

Figure 4 illustrates a graphical representation of the total design costs in terms of hours for the design.
One adjustable bike pedal desk was made to help students get their wiggles out without disrupting other students. Also, being able to work on class work in Paige Boone’s classroom. The desk and bike pedals have given the students a resource to accomplish staying on task during class time while simultaneously moving their legs on bike pedals.
How to build
The following two tables are step-by-step instructions on how to build an adjustable desk and pedal system.
Maintenance is not the most important thing in order to keep the pedal desk looking pleasant and functioning properly. Very little regular maintenance should be required for the desk due to the mount of use.
Maintenance on the bike pedal desk does not follow an exact schedule. If so, a daily task would simply be to wipe the desk top off at the end of the day when normal maintenance crew cleans the classroom. However, if something where to come apart the easiest fix would be to insert a new screw in the same location or near the same screw. As for the pedal the only maintenance it will need is when it starts to make any squeaking noises. The best way to resolve this problem is to apply WD-40 in the grease hole near the pedals.
- Wipe down the desk top to disinfect any bacteria and to take off any marks that previous students made.
- Long Term
- Check the pedals to see if it needs oil, if so apply the oil in-between the pedals in the oil hole that’s included.
The following table is a guide that details some common problems found with pedal desk users and solutions to each problem.
|Desk gets marked up||Wipe/scrub surface|
|Pedal begins to make high pitched noises||Apply WD-40 to squeaking area|
|Whiteboard starts to come off||Add super glue|
Discussion and next steps
Team EWM worked collectively to accomplish the construction of the bike pedal desk system. Through the process our team members have gained skills working as a group, communicating with a client, time management, being accommodating, and stepping outside of our comfort zones.
Suggestions for future changes
- Instead of using wood, use metal pipe and weld it to the bike frame for a stronger joint.
- Manufactured pedal systems cans be found inexpensively on the internet.
- Try to make the best cuts when cutting the bike frame.
