A Leitra velomobile redesign by Kuba Szankowski
For his final project in Mechanical Engineering at the Danish Technical University, Israeli born Danish citizen Kuba Szankowski designed a velomobile based on the classic Leitra design. He worked closely on the project with Carl Georg Rasmussen of Leitra, who “at eighty years young still builds and maintains all the velomobiles, as well as most any…

Evolution of the Windcheetah- a guest post by Karl Sparenberg
I am a big fan of Mike Burrows, and have mentioned his work quite a few times over the years at Bicycle Design. In 2012, lifelong “cycling fanatic” and engineer Karl Sparenberg of Advanced Velo Design took over production of Burrows’ Windcheetah recumbent trike, and has been working on improving the materials and manufacturability of the…

Predator HPV by Eugen Ackermann
Last summer, for his Bachelor thesis of Industrial Design at Pforzheim University in Germany, Eugen Ackermann chose to design an “Alternative Mobility” solution. His Predator design is a recumbent bike, a category that he believes offers users many advantages but still is not socially accepted even though the basic design goes back to the…

Velomobiles (or whatever you choose to call them)- part 2
If you missed last week’s post at Bicycle Design about velomobiles, be sure to check it out. In addition to the links that I mentioned in the body of the post, a few of you shared additional interesting velomobile designs in the comments section. I ended that post saying “whether you call them velomobiles, HPVs,…

Velomobiles from Piximatic and GeoSpace
It has been several years since I mentioned Christophe Sarrazin’s velomobile designs. Since that 2009 post though, his website has evolved quite a bit. The site is more than just a source for news about velomobile design. To encourage others to get involved with velomobile construction projects, Christophe offers free downloads of many of his…

ZIPcycle 2.0 by Eric Birkhauser
Eric Birkhauser’s “open air” ZIPcycle velomobile concept was featured in a Bicycle Design post last year. He points out that the feedback received from readers in the comments (and from an earlier post) directly led to his redesign… the ZIPcycle 2.0. In order to prove the concept, Eric’s next step is to build a working…

A GrabCAD contest and a bit of HPV history
I briefly mentioned the engineering website and community GrabCAD last year, when they ran a crank weight reduction challenge for Tern and a bar tape fixing challenge for Flying Machine Bicycle Design Studio. They have a new design/engineering challenge underway, in partnership with Velodroom, to “create an accessory that solves a problem cyclists face in…

City Speeder recumbent by Roel Verhagen-Kaptein
Fresh on the heels of my last post, we have a reader submitted design from Roel Verhagen-Kaptein (perfect for a day like today when I am pressed for time). Roel explains that the City Speeder is “a recumbent bike made for commuting in a fast and comfortable way. The streamlined body makes the bike fast and…

VeloTilt: Design of a low drag practical velomobile
Recently, Arnold Ligtvoet from RaptoBike sent me a link to an interesting project that he is involved with. The goal is to develop a velomobile that is both practical and fast, and the team that is working on the VeloTilt certainly has the credentials to make it happen. The development team consists of Will Schermer-…

InCog multi-tool and more
InCOG is an “out of sight” multi-tool that was created by Industrial designer Joshua Brassé, Founder and CEO of Ideacious. The tool fits neatly inside the bike’s handlebar, and is flexible so that it works with standard drop bars as well as various other bends. The exposed end-cap is designed with a recessed star pattern,…

Mohsen Saleh, a design engineer living in Milan, Italy, has been working on a rear wheel steering recumbent bike design (in his spare time) for about a year. In a recent post on his blog, Mohsen explained his three main objectives for the project: To eliminate the long chains used on current recumbent bikes To…

Dave and Rob’s custom trike
After seeing the post yesterday about the DuoCycle, Dave Thompson sent me this picture of a similar trike that he designed and built for himself and his son. Dave’s son Rob was in a car accident three years ago and suffered a severe head injury that left him in a wheelchair. The trike Dave built…

Rain Bike by Frederic Boonen
If you have been reading this blog for a while, you will remember Torkel Dohmers’ “ThisWay” concept, the winning entry in the Bicycle Design “commuter bike for the masses” design competition a couple of years ago. You may also remember that the pick was not without controversy. People seemed to either love it or hate…

FlooW and more
I’m still slammed with work after a couple weeks out of the office, but I want to quickly pass along a few links of interest. I don’t have a lot of information about it, but FlooW is a pretty interesting mobility concept. You can read more about this high tech recumbent quadricycle design (in Dutch)…

One of these trikes is not like the other
A reader, Tim, who owns a Baccura Airlite from the last batch made, describes it as “a beautiful lean steer trike that mimics the simplicity of a bicycle.” Baccura.com, an unofficial site that was “developed to showcase the lightest, fastest recumbent trike ever made” refers to it as the “only successful lean steer trike design…

New and old pedal powered monorails
An Inhabitat post this week pointed outs that Google is investing $1 million in Shweeb, a company working on a pedal powered monorail system. The company was selected as the “innovation in public transportation winner” in Google’s Project 10100 program, which aims “to change the world by helping as many people as possible.” Shweeb has…

OOPHAGA trike and a homebuilt wooden frame
I’m back from an extended weekend of mountain biking and kayaking at Tsali. I didn’t have (or want) phone or Internet access while I was out in the woods, so I am just now starting to look at some of the coverage from Interbike last week. Bike Rumor is one place where I have found…

Friday links
It is Friday afternoon, but I’m still pretty busy trying to wrap up a few things before the workweek ends. While I have been focused on a couple of big projects this last couple weeks, the bike related links that I have wanted to share have been stacking up. I guess that means that it…
