Amidst a tangle of bike and rack bars

How to make a hard saddle bag from recycled plastic jars. Full article at


Gerry :)

I drilled two holes in the deck so I can bolt-on a large plastic bin when required.

Each rider powers one wheel...if you want to turn, one pedals faster than the other.


Most people entertained themselves by spinning in circles as fast as possible.

Gotta get to work somehow.

Once the piece was cut to size, I trimmed away the destroyed, frayed edge of the fender and installed the replacement piece with zip-ties. I LOVE zip-ties.

Quando tentei aperfeiçoar o protótipo, fiz caquinha e perdi o protótipo (na verdade porque notei um erro no corte inicial)

Resultado final. Meio torto, mas é um protótipo ainda

Dando um trato no visual. Faltou lixar as rebarbas

The studded winter tyres wouldn't fit inside the summer almost-180-degree mudguards so they had to come off. I put an old MTB crudcatcher on the front.


On the back is another MTB mudguard that wouldn't fit in the proper place, but instead is zip-tied on top of the rack (so the lever bit will still lever). And, taking inspiration from BikeHacks, there's a water bottle cut in half to fill in the gap by the seat post. It works very well.

First draft of part of a set of 3D-printed adapters to attach a Topeak trunk bag to a generic seatpost clamp beam rack. Fits rack perfectly after thumbing a few burrs off the inner surface. I still need to re-measure/re-shape the guide rails that grip the bag - they're slightly too narrow.

Na segunda tentativa marquei as linhas de corte para facilitar

Mudguard not giving enough splash coverage? Simply cut open an (organic) beer can and gaffer tape it on!

Como o paralama ficou muito mole, fiz um reforço estrutural com uma tira da própria garrafa

Partindo para a segunda tentativa ;) desistir jamais!

Plastic display card for a WTB saddle. I cut two pieces and doubled them up inside the fender end for extra support.

Isso ficaria escroto! Então desenvolvi o protótipo 01

Hacked together from an empty Alpen cereal box and an old DHL envelope.

Turn right, go left.

Both similar Trek bikes, but there are some differences like the forks, tyres, brakes and mudguards.


Anyway, look at the front wheels for the answer to the question!

Childs trailer with the top-section unbolted and all the fabric removed.

This is not the donor bicycle . I repaired it and gave it away . This is an example .

Little bike hack: one of those snap-on wrap-around arm-band reflector things around the wheel axle.


Keeps the hub clean and the bike visible.


You can also use a zip tie or a pipe cleaner. See
