Same for me. I ride 700x28mm Schwalbe Marathon HS420 performance in front at 85 PSI and a 28mm Schwalbe Delta Cruiser reflex at the back at 65 - 70 PSI (It can allow as low as 55 PSI according to the manufacturer spec on the tyre). I weigh an average about 69 Kg (151 pounds). This is a good...

I'am trying to understand the incident. Do you mean the rear wheel literally came off from the and the rear dropouts touched the ground? Did the skewers break?

Looks like you went back to 28mm or sleek 32mm tyres! You really must be getting a hang of it now!

.. for me I'am more scared riding my recumbent on extremely congested roads like these because quick starts and stops are harder for me on my recumbent than on the DF. I also feel psychologically more vulnerable because I'am seated lower and with slightly wider handlebars and I cannot jump the...

The wide lens of the action camera makes it look worse than it really is. However, I still choose my routes to avoid highly congested roads. Being a weekend it was alot better. On a week day, it's absolutely crazy. I can only dare ride it with an upright for my commute. Here is an old video on...

@Emeljay! Iam honored! Its the one pictured above on "Critical Mass Nairobi" photo. Its a DIY steel bike.

... and another weekend ride:

Yes, considering the weight of these bikes, the triples are a must for steep or long hills. However, unless the grade is greater than 4 - 5% or very long, we rarely use the granny gear. (My cassette is an 8-speed Sunrace 11-34 and my crankset is a 50-39-30 Shimano Sora. I use barend ratcheted...

Great observation! Yes, he cut off the old BB from the original U shaped ladies donor bike and MIG welded the frame back together. Mine was a suspended Y-frame "step through" ladies bike. I just welded a seat stay and removed the suspension. Generally, step through cromoly/steel ladies bikes are...

We both have steel framed DIY MBB bikes modified from old bicycles. Quite heavy and not for the faint hearted! :p. Mine weighs 18Kg yet it is noticeably lighter than his! I guess his is more than 20Kg! Funny thing is that he climbs better than me despite the extra weight! We could both make...

Here is to more innovations and refined recumbent bicyles! This is my ride to start the year:

Just curious, what seat recline angle have you set on it? Looks like 40 degrees or about 35.

Great work Marco! I believe the bottom bracket is deliberately low for better blood flow to the legs and better orientation for pushing when climbing?

In my humble opinion, I don't think a limited custom built copy for an individual is an infringement. It is the large batch production for sale using exact copies of the design that may be challenged. In that case you should design your own and check for any patent infringement. That is for...

I think the curve also reduces that problem. I remember John Tolhurst talked something about fit for a wider range of people.

I think MBB FWD recumbents design are not an exclusive copyright to cruzbike. I believe anyone can manufacturer an MBB FWD recumbent. However, to the best of my knowledge, the telescoping boom design for an adjustable front triangle is a copyright and patent of Cruzbike Inc. I also believe...

I think that Titanium bike looks good. My only concern is that I think the head tube looks short. But if it is long enough to form a good welded joint with the main down tube then it's acceptable. I wonder how much it weighs? If the complete bike is anywhere near 10Kg or less then it's worth...

Your videos are always very well presented Marco! Nice agile bikes those ReVs!

In short it was to allow the front derailleur to adjust independently of the boom length changes. And now the the long version: The first version of the Silvio version 1.0 or the predecessor of the S40 and the vendetta had the boom straight and front derailleur attached directly to the boom...

Would you consider a triple? 50/39/30 like Shimano-Tiagra-4703-10-Speed-30-39-50t-165mm-Crankset works with Hollowtech II Bottom Bracket. https://www.ebay.com/itm/NEW-Shimano-Tiagra-4703-10-Speed-30-39-50t-165mm-Crankset/191904181708?epid=1046122428&hash=item2cae616dcc:g:I4YAAOSwGPxaAeu8
