This basic tutorial will cover cutting a simple 90 degree fishmouth into round and square tubing. A fishmouth is a semi circular cut taken at the end of a tube so that it can be joined to another round tube. In bicycle frame building, it is often necessary to cut several fishmouths into the ends of the steel tubing where the head tube or bottom bracket will be installed.
Mini bike chopper from Russia “Hello. My name is Aleksadr. I am from Moscow, Russia. I send you a photo for your gallery of builders. It’s a mini chopper I made for my son for school. I will be very glad if you put our mini chopper in your gallery. Viewing your photos has inspired me on construction of it.”
“We are Bristol’s most comprehensive Community Bike Project, repairing and relocating unwanted bicycles. We aim to help people from all walks of life get out on two wheels and for it to be an inclusive and empowering experience in the process.
Through our weekly workshops, we provide ‘free’ bicycles to members of underprivileged and marginalised groups that would not otherwise have the opportunity to own one. The Project combines a surplus of unwanted bikes (most of which are otherwise destined for landfill), volunteers of all abilities who are able to develop their mechanical skills within a supportive and safe environment and marginalized people within our community in need of affordable and sustainable transportation.
We are a welcoming and inclusive community-based Project, encouraging skill-sharing, promoting sustainability and helping people help themselves.”
“They’re finally done. When me and wife ride these down the street they generate a lot of second looks. She calls them our lazy-boy bikes because they’re so comfortable to ride.
While building these I looked around the internet for alternate ideas, but always returned to Brad’s design. I’ve seen other trikes that cost over $1,000 that don’t look as good as these. Well done, Brad & Kat.

Awesome on both counts, Mark. You and your wife are certainly riding in style. Well done!
“Here is my RD bike. I built it about four years ago. This is a four speed, two forward pedal gears and two back pedal gears.
“Scout” is a solid commuter/townie as well as an intrepid explorer. The transmission was patented in the 1880s, so it’s nothing new. I’ve pedaled Scout forwards and backwards thousands of miles and it just keeps going (forward).
“Your new stomping grounds look great. I hope you fill all those acres up with new creations. Thanks, Joe.”
“I was doing my dawn ride this morning on my upwrong (I have been alternating every other day between my DF and recumbents to give my butt a chance to recover as I get back in shape). I was cruising along when I spied a red recumbent with a yellow front fork going the other way. I went by too fast to get a good look, so about 1/4 mile later, I decided to turn around and catch him to take a good look.”
