Bike Friday HaD: Portable Tools and DIY Roller Wheels

Finally, to make the Bike Friday Haul-A-Day cargo bike ready for active service, I need to add some tools to make it self sufficient, in case something happens while out riding. Then, to make it easier to wheel the bike around when in the vertical position, I added some roller wheels to solve this problem.

There are many ways to carry tools on the bike, especially on this cargo bike where there is plenty of space. However, as far as possible, I want to avoid using the side bags, and instead fix the tools onto the frame of the bike itself, so that it does not fall out or need to be removed.

As saw earlier when studying the frameset in detail, there is some space at the rear of the frame where a bottle cage can be mounted. This is where a tool bottle can be stored, to hold tools and spares inside, using a bottle cage.

I had this Specialized SWAT EMT tool, for almost a year already. However, I did not get to use it as all my other bikes already have some sort of spares and tools system in place already, and this is an extra set of tools. Now, I have the chance to use this! Let's see how this bottle cage and tool combination works.

Specialized SWAT EMT Tool. Basically the tools can be mounted below the bottle cage.

The portable tool kit, with all the essential tool bits and a holding bracket.

Fixing the tools onto the holding Bracket. It was a little tricky mounting everything onto the frame, together with the bottle cage.

The bottle cage, together with the tools, is mounted at the bottom side of the frame. This creates space for mounting other accessories on top.

Other than having spare tools for making adjustments, there are a few things needed to repair a puncture. Tire levers, spare inner tube, and an air pump. These three parts are essential, because if one part is missing, the other two are useless.

The tire lever and the spare inner tube can be stored in the tool bottle, but I need to find some space to install a portable pump. I am not able to install the pump mount directly to the mounting holes, as there is interference with the frame. 

Looking through my spare parts, I found the Shimano Bottle Cage Adapter, SM-BA01. This will allow the bottle cage holes to be offset, so that I can mount the portable pump on the frame.

Using the bottle cage adapter to offset the bottle cage holes, so that I can mount the Lezyne Pressure Drive onto the frame. This pump was previously mounted on the Brompton M6R.

With all the tools mounted together on the frame! This is additional weight, but since they are fixed to the bike, I will not need to remember to bring them every time.

With the portable tools mounted successfully, I can now focus on the last outstanding issue at hand, which is also the most tricky.

Whenever I need to bring the bike out of the house to ride, I need to wheel the bike vertically into the elevator. The problem is, when the bike is vertical, it is very difficult to move the bike, as it is heavy and there are no roller wheels.

There is no ready made solution, and so I have to create my own DIY system to allow the bike to be rolled around easily when vertical. After testing a few different ideas and configurations, this is the final setup that works well.

The parts needed to make one side of the roller wheels. 2 sets are needed since 2 roller wheels are necessary to balance the bike.

These parts are specifically chosen to work with each other, with the most difficult one being finding suitable roller wheels.

The roller wheels need to be the non-swiveling type, with mounting holes. They also cannot be too big or too small. Then, the holes on the mounting plates should match the holes on the bracket of the roller wheels. Finally, the black bracket is used to stabilize the roller wheels so that they don't move around when under load.

Final setup shown here. Looks quite elaborate, but it is necessary to ensure that the roller wheels are well supported from all load directions.

The roller wheels are clamped onto the frame, using 2 sets of plates, plus standard bolts and nuts.

One of the set of plates has an L-bend, which is then clamped with the black bracket. This prevents the plate and thus the roller wheels from collapsing when under sideways load.

Finally, the black bracket is secured onto the bottom of the frame, with 2 adapters to allow the diameter 31.8 mm bracket to be secured onto the frame (about diameter 25 mm).

Roller wheels plus the ends of the wraparound bars supporting the full weight of the bike when placed vertically. This is also the condition during vertical storage.

These roller wheels are not of really good quality, as they are simply plastic wheels with no bearings or rubber coating. The metal sidewalls holding the roller wheels are quite thin as well.

I would say that the weak point in this setup are the roller wheels, as the wheels are not of good quality. However, I could not find any other better roller wheels with suitable dimensions for mounting.

Initially I found that the roller wheels cannot roll smoothly when under load, which happens when the bike is being moved around in the vertical orientation. However, after I added some oil to the roller wheel axles, they became a lot smoother.

With the roller wheels, I can now wheel the bike vertically without any trouble. It is a lot easier compared to without roller wheels. The bike is now completed, with no planned additions or modifications in the near future.

Bike Friday HaD: Side Bags, Lights, Mudguards

Other than the accessories for carrying the child, there are also other accessories which are necessary for safety and comfort. On the Bike Friday Haul-A-Day cargo bike, there are massive side bags available for carrying cargo. These bags will also be useful when bringing the kid around, as their legs can slot inside the bags.

Big side bags by Bike Friday, which are specially designed for this bike. Weighs almost 600 grams for the pair.

Side bags mounted, one on each side. Other than hauling cargo, it also prevents the child's legs from touching the rear wheel.

When not in use, it does not add to the bike width at all. The widest part of the bike, other than the handlebars, will be the kick stand and wraparound bars.

The bags are ideal for the child's feet to rest inside, to secure the legs and help the child to stay balanced and upright.

These side bags can expand a lot, and can fit even a big school bag such as this.

When parked vertically, the side bags will more or less keep their shape. However, small items will fall out from the back as the rear of the bag is not fully covered.

When the bike is vertical, the holes at the rear of the side bag will allow items to fall out.

The side bags are super useful, as they can carry a lot of things with no fuss. Helmets, kick scooter, big bags, etc, no problem at all!

It is also good to install front and rear lights on the cargo bike, even though it will mainly be used in day time only. You never know when you will end up using it at night when it is dark.

There are many ways to mount a rear light, but I decided to mount it under the metal plate, using a tube to simulate a seat post. It is actually just a QR Axle Extender.

It is bolted to the metal plate via just one screw. Since it is hidden under the cushion, it is no problem.

This rear light is similar to the Moon type, but it is of the Entity brand, which is Polygon's own house brand.

The rear light wraps around the tube using a rubber strap, same as if it is strapped to a seat post.

Rear light is placed in a very visible spot, but it is also well hidden from damage, even when the bike is parked vertically.

Front light is a Moon Nebula W, which is bright and powerful, while also slim and lightweight. It straps onto the handlebar easily with a rubber strap.

Finally, the mudguards will also be installed. Weighs 452 grams for the set including all hardware.

As the SKS mudguards are from Bike Friday, they have been customized to fit the Haul-A-Day nicely, without any further DIY work necessary. Instructions for installation have also been included.

Front mudguard installed, with plenty of tire clearance. Spacers are needed under the bolts, to create clearance with the brake calipers.

Rear mudguard installed. Quite tricky to install with the rear wheel and side bags in place though.

No issue bringing along a kids bike as well!

Bike Friday HaD: Accessories for Young Riders

The main purpose of this Bike Friday Haul-A-Day cargo bike is to bring my kid around, therefore a few other accessories are needed to make it child friendly. If it is just for hauling cargo, a different set of accessories will be needed.

These additional accessories are available from Bike Friday as a Younger Rider upgrade package, to make it easier to get what you need. I think it is also slightly cheaper if you get it as a package, instead of getting the parts ala carte style.

When I collected the frameset from MyBikeShop, they have already pre-installed the wraparound bars and the foot rests.

At the front of the wraparound bar, it is connected to the frame via this connecting bar.

At the rear, there is another bar that joins the ends of the wraparound bar to the frame, plus another cross bar that links the left side to the right side. This additional bar prevents the child from falling off the back of the bike.

Underneath the cushion is a metal plate, industrial style.

Here is how it looks with the cushion removed. Not comfortable to sit on though.

The metal plate is fixed to the frame via a few nuts a bolts. There are many additional holes on the metal plate for adding other accessories if necessary.

The foot rests are big, and there is one on either side.

The foot rests are not fixed to the frame via any bolts, just via spring loaded knobs.

A strong kickstand is also necessary to load and unload the child safely. This unique kickstand wraps and rotates around the frame itself, so it is very strong. The bolts cannot be tightened fully or it will not rotate.

The black stopper of the kickstand rests against the frame when extended, making it very stable.

There is a bungee cord that retracts the kickstand, but it slips off the kickstand easily. I added a metal hook to hold it more securely.

The whole rear half of the frame, including all the accessories, weighs a massive 9.2 kg. This is heavier than many full bikes!

The foot rests are not needed now, as the child cannot reach it anyway. I removed them to save weight and also reduce the bike's width.

The cushion is also part of the package, designed to fit the metal plate perfectly.

Enough space to seat two to three kids!

The package includes the wraparound bars, the supporting black bars, the metal plate, the cushion and also the foot rests. The side bags are also included but are not shown here. The kick stand is not part of the package but it is necessary for parking the bike and also for stability during load and unloading.
