China3D printingNet October 8th, this week is an exciting week for 3D printed bicycle enthusiasts. Urwahn Bikes announced plans to produce 50 stylish limited-edition electric bicycles. British engineering company Renishaw revealed its Role in the success of the Olympic cycling race.
As for the former, Urwahn Bikes announced the collaboration with MCM designers to develop “MCM EDT”, a luxurious SLM 3D printed electric bicycle. At the same time, Renishaw disclosed how it participated in the manufacture of the “innovative new track bike” called “HB.T” to ensure its light weight and sufficient aerodynamic performance to allow GB team athletes Reach the highest speed at the Olympics.
Ben Collins, a design engineer at Renishaw’s Additive Manufacturing Group, said: “It is exciting to see Renishaw’s additive manufacturing expertise played a key role in the UK’s promotion of the Tokyo Olympic gold medal.” “The team won. Won three gold medals, three silver medals and one bronze medal. This is a brilliant achievement for cyclists and an excellent display of the advantages of additive manufacturing.”
Renishaw’s Olympic assist
As the official supplier of the British Cycling Team (GBCT), Renishaw was first requested by the British Cycling Team in early 2019 to use its expertise to produce the then unpackaged HB.T tracked bicycles.In particular, the organization is seeking to use the company’s 3D printingAcuity, the innovative front fork and seat stay are integrated into the bicycle design while keeping it light enough for legal competition.
To achieve this goal, Renishaw quickly produced plastic and metal prototypes in the early stages of HB.T’s development to ensure that its parts are lightweight, geometrically accurate, and durable enough to withstand the pressure of riders. Once the bicycle passes the preliminary tests, the company will deploy the RenAM 500Q system to 3D print the aluminum and titanium parts of the bicycle, such as handlebars and rider-specific parts.
In the end, Renishaw stated that its contribution allowed Lotus Engineering and Hope Technology to build a working prototype fast enough to achieve success in the first round of the Track and Field Cycling World Cup in November 2019.
From then on, as they said, the rest is history. Riding on the 3D-printed optimized HB.T, cyclist Laura Kenny became the most successful British women’s Olympic athlete ever in Tokyo, and won the Madison gold medal with Katie Archibald , And won the silver medal in the women’s team pursuit. This bike also helped Jason Kenny become the most successful Olympian ever in the UK. He had previously won a gold medal in the Kailin race and a silver medal in the team sprint.
“When you have the courage to try new things, you will encounter many difficulties to overcome, and this is what makes Renishaw outstanding,” added Tony Purnell, the British bicycle technical director. “In the past, it took months to get from the drawing board to the work you can try on the test bench or the racing track, but now we can finish it in a few weeks.”

In other bicycle news, German electric bicycle manufacturer Urwahn Bikes announced its latest foray into the field of 3D printing, namely MCM EDT. The company has been producing bicycle frames in this way for at least two years. Initially, in cooperation with motorcycle brand Vagabund Moto, in 2019, it added 100 frames for its “Stadtfuchs” custom bicycles, and then launched one in 2020. A new racing car.
This sports bike was developed in cooperation with Schmolke Carbon, a high-performance bike expert. It uses 3D printed steel frames and carbon fiber parts. Its price is as high as US$9,369, which reflects this. Urwahn bikes later continued to 3D print a unified frame for AREVO’s Superstrata, and then did the same work for the “Platzhirsch” electric bike, which was roughly named “Big Cheese” due to its huge power output.
Based on this high-end electric bicycle manufacturing experience, the company now cooperates with MCM to develop a city bicycle that celebrates MCM’s 45th anniversary. The result of their joint efforts is MCM EDT, a unique copper-plated bicycle that has earned it the apt nickname “Golden Horse” in some respects.
The automobile company MAHLE also participated in the construction and added a 250 Wh battery to the bicycle’s pipeline to provide it with enough electricity to travel up to 80 kilometers on electric. This range can even be extended by another 60 kilometers. Although the bicycle’s 3D printed frame is rarely disclosed, its integrated belt port, flat mounting and cable routing will surely be vital to its lightweight posture.
Taking into account these high-quality specifications, the level of fine-tuning in the manufacturing process, and the luxury bikes before Urban Bikes, the high price of MCM EDT is expected, but the price is 10,960 US dollars, and only 50 vehicles are produced. e-bike is likely to represent the company so far The most unique (and gorgeous) product to date.

AM-driven bicycle performance
Unsurprisingly, given the ability of 3D printing to integrate multiple parts into a single lightweight part, this technology has been increasingly used in bicycle manufacturing over the past year. In March 2021, the bicycle brand Silca launched a 3D printed titanium computer stand, which is stronger, lighter and more aerodynamic than traditional alternatives.
Similarly, Headmade Materials collaborated with Service Bureau Element22 earlier this year to develop metal SLS 3D printed bicycle pedals. The upgraded pedal will be mass-produced under the Titanium brand using the former’s cold metal fusion (CMF) technology. It can be ordered initially through Kickstarter and has raised more than 59,000 euros.
Just like Urwahn Bikes, Huhn Cycles also caused a sensation in the 3D printing industry with its bikes that won the Purmundus Challenge. This unique bicycle is called Moorehuhn, and its frame is made of lightweight titanium tubes connected by 3D printed lugs, thereby increasing the rigidity of the connection points, thereby increasing the overall strength.
