This is not a unicycling activity. We will be volunteering as a team to assemble bicycles in Downtown San Jose.Big Bike Build is an annual event hosted by TurningWheels for Kids. TWFK's mission is to distribute bicycles for the holiday as well as year round focusing on preventing childhood obesity and supporting low-income families.

There is a $40 fee per person to participate.

On that day, hundreds of volunteers (made up of many teams just like us) get together to assemble over 2,000 department store type bikes for underprivileged children. Most of these bikes are almost ready out of the box so no special bike building skills are required.

These bikes come in boxes and are partially assembled so our job is pretty straightforward and no special bike-building skills are required. There will be an experienced QC volunteer (called the "Wrench") assigned to our team to help us with issues and QC our bikes. Speaking of QC, keep in mind that the recipients of these bikes may not have the resources to pay for repairs should they fail. So we want to take our time and do our best to build them right before we send them off.

There will be a range of bikes from little kids to adult size to build. You can choose what to build. If you can bring a folding table or bike repair stand, that would be great but not required. A lot of people just do the build on the concrete floor (bring knee pads if you have them). It's also possible that there are tables available onsite.

Below is a list of recommended tools. Labeling the tools you bring is recommended since tools tend to wander away. Note that we won't have access to power outlets so plan on using hand tools only.

Don't worry if you don't have everything listed, there will be tasks you can help perform without having all the tools.

Tool list:

Floor pump (preferably with air pressure gauge)

Metric allen wrench set: 4mm, 5mm, 6mm

Open-end box wrenches: 8mm, 9mm, 10mm, 12mm, 13mm, 14mm, 15mm

Medium and large size adjustable wrenches

Small, flat blade screwdriver

Phillips screwdriver

Deep 3/8 drive sockets: 15mm, 18mm, 19mm (for bikes with pegs)

3/8 drive extensions and ratchet wrench

Pedal wrench (normal thickness wrenches do not always work)


Utility knife

Wire cutters


Bike work stand or folding table

Truing stand

Spoke adjusting wrenches



Parking is at the multi-level parking garage next to the event site. We can use the lower three levels. Space is limited so arrive early if possible. The garage will be open at 7:30 am. Tell the attendant you're here for the Big Bike Build. Note that we are only allowed to park there until 5 pm. The garage is about one block from the entrance to the event site so if you have heavy stuff, arrange for drop-off or use some kind of transporting aid such as a hand truck or dolly.

Parking garage:488 S Almaden Ave, San Jose, CA

We'll meet at our assigned corral. To find our corral, look for the corral map posted near the entrance and locate "Silicon Valley Unicycle Group".


Lunch will be provided and served just outside of the building so dress in layers just in case. As of now, we don't know if breakfast and coffee will be available (will update later). Due to restrictions imposed by the building manager, technically, there will be no food or drinks inside. However, we can have bottled water and prepackaged food bars inside.


7:30 am door opens (parking garage opens)

8 am recommended arrival time (setup)

9 am kickoff

11 am trike race (open to all adults; purchase ticket; bring helmet)

12 pm lunch

4 pm (or until all bikes are built; usually sooner) finish & help cleanup if needed


Bikes in boxes will be stacked along the center aisle arranged from adult geared bikes (near the entrance) to little kids bikes (towards the back). You are free to pick what to build.

When unboxing, make sure to empty all the content before you start building. The trash team tends to be very efficient and may take away open boxes with parts still inside. We want to avoid building Frankenbikes.

Place empty boxes at the edge of our corral (within our taped borders) for pickup by the trash team. Make sure they don't block the aisleway.

Be careful with tools. Wearing gloves is recommended. Most injuries have been cuts from opening boxes. First aid station will be onsite.

We are requested to set the saddle height to expose the seat post about 5" (if possible) to make it easier for QC to clamp the bike on the service stand.

Some bikes come with training wheels. Make sure they are adjusted properly. The bike needs to have a little wobble when placed on flat ground. Otherwise, it may become a "stationary bike".

Although the building is enclosed, it's a big open space so it could be chilly. Dress in layers just in case.
