Neither can we!

I wish I had the newer geo on my BFE but I am glad I got the old head badge.

You can still buy the old head badge 😊

I'm amazed Cy hadn't realised how unsound titanium is.

Neither did we until very recently.

@@CoticBikesUK I had been surprised that you were using the material. It never occurred to me and others that you just didn't know.

@@jeremyatkinson4976 We keep learning and keep trying to be better. Ti has a lot of nice features for longevity once it's actually made, we just didn't understand what lay behind that until the Reynolds work.

Thanks for having me Chris. Any questions about what we chatted about, drop a comment. I will be around to answer them. Cheers, Cy

Talking to old riders, steel framed motorbikes used to be renowned for being flexible but in a bad way. Common comments are along the lines of like riding a rubber band. When manufacturers started making frames from aluminium it made them a harsh ride, it took a short while for them to get that right. Apparently it was particularly noticeable on motor-cross bikes. With modern design and manufacturing techniques it makes sense to revisit steel frames again. Even early aluminium mountain-bikes used to be a hard ride compared to steel. I have a couple of titanium hard-tails and they have a spring to them vertically but seem stiff laterally. Do you experiment with different tube joining methods? Butted verses sleeved, gusseted and brazed? It would be interesting to use a modern electric brazing method where the brass filler actually alloys with and penetrates through the steel rather than just acting as an adhesive as it does with gas brazing.

Steel has definitely come a long way, and you can undoubtedly have too little stiffness even if the bike is strong enough. We play with different tube specs, but we haven't explored different joining techniques for steel

Really great interview! Interesting to hear about supply chain issues from a business point of view and the way it impacted relationships with the taiwanese builders. I hadn't heard about that in quite as much detail before. After the conversation about the flexy steel rear ends i'm curious, were the drop-link bikes ever tested with a completely steel rear? If so what about the aluminium swing arm made it the final choice? Also great to hear that Cotic is doing okay, I got a FlareMax back in January as i'd been dreaming of a Cotic for a while and things seemed a bit uncertain. Glad I did too it's been awesome.

@@Zedcky Firstly, thanks for getting a Cotic. That's fantastic. We did actually prototype a steel swingarm, and the weight was about the same as the aluminium version, but it required a lot more parts to make, and a lot more welding and fabrication. Our Taiwan vendor gave us a very high price for doing steel, and much lower for aluminium because we could use large forgings for the swingarm head. This massively reduced the complexity compared to making small steel CNC parts and welding them in multiple places to tubes. We are very happy with that decision. The aluminium swingarms are tough, consistent and work really well.

Not a question, but I finally pulled the trigger on a bfe frame after listening to this. It's replacing a frame from a brand with no values or personality outside of their faceless corporate identity. I appreciate what Cotic, and similar brands, are doing and I can show that by riding one of these bikes.

Just like the lithium batteries in E-bikes carbon fiber frame recycling will become more of a thing. Just because neither are done on scale at the moment does not mean that it will not happen in the future. Both are already done just not on a large scale. Several manufacturers are using carbon fiber waste to make saddles, tyre levers, bottle cages etcetera and i think i have even seen one manufacturer using chopped waste fiber to make rims from. Poo pooing carbon fiber whilst promoting lithium battery powered E-bikes is a bit hypocritical.

There is no easy answer, and I agree that battery recycling is a real problem that needs better solutions. We are looking at the possibility of using end of life ebike batteries as power banks at work, but there are no off the shelf solutions. The other side of ebikes is that it's getting more people cycling, and helps reduce car usage, increases active travel. Even having enduro spec ebike prototypes, we all ride to work more as a result of having access to them, so whilst batteries are a problem, e-mobility is part of a bigger solution to transport and health issues. Carbon recycling is possible, but it's very energy intensive and generally involves burning off the plastics which creates toxic by products. The resulting recovered fibres can only be used in very low grade applications. Metals can be recycled almost indefinitely and can be reused in high performance items.
