I've not read all the posts, (I don't usually). But I have four trikes, all tadpole as the Warrior. None has a rear brake. You don't need one on the rear wheel. If you want a parking brake, just put an elasticated band on one of the front levers. My Carbon trike has this. It holds. Another trike...

Yes, strange lot these HPV'ers, (me included I suppose). The Snoek is a fish too, and a velomobile. One of the BHPC trophies is a fish! Picture Covid era 2020, not bandits! Martin.

Number 556, that's a TUNA 3-wheeled velomobile, made in Holland, based on the DF-XL, but improved. First time I've seen one. It finished 3rd in the 3-hour race. The blue and white one is a DF-XL, 592, and came in at 30th in the race. The other TUNA positioned 9th, so they are fast machines. Do...

Well, how did I do at the HPV World Champs 2024? Very well for an old geezer. Things didn't go well in some races though. I miss-geared while doing the 100 metre Standing Start Sprint, but tried to recover by stamping on the pedals (a no-no)! I did 16.4 mph. This would have put me 15th out of 26...

Hi Tillerman, apologies for not seeing this earlier. Do you still want the STL files?

You little tilter...

I use Cateye Strada Cadence. It's wired-cable, which suits my carbon bodied trike as wireless signals wouldn't get through. The cables are long enough for recumbents, important. It's easy (old school) to use rather than modern cluttered versions that are really for bikes. It's old and mostly out...

I don't know what the gain will be, that's why I've used wood, not exotic composites. Some say the speed increase is between 1 & 2 mph. I noticed about a 2mph gain with a front fairing, but with a 2 kg plastic lump onboard, it compromised my cornering ability. The fairing is a fleeting look-see...

In progress, trike back fairing for anyone who might be interested or take inspiration from it. It's made from wood, destined to be covered in model aircraft shrink plastic. Wood is used as it's light for the given strength plus I've got a shed load of 8x6 feet 1/16" plywood. I also used 3mm...

In 2004, Mike Burrows (RIP) did experiment with a FWD no chain, "centre wheel steering" 2 wheel recumbent. It worked, but his was twitchy and in racing he did crash it, giving him some gravel rash. Reference from his book " From Bicycle to Superbike", page 164. Try it, but be wary with a low...

Zipp one gives better steering as the chain pivots about the steering axis. Need up to ±20° for some corners! The one pulley is for a 2 wheeler!

At last some UK council(s) or whoever are thinking, A to B, is not just for cars! Martin.

Found this, might be useful. Six years old vid. linear pedal cycle. Not only Exacta-Tech But also, Doesn't have to have an exact linear travel, can arc on a pivot too. Essentially at the heart is 2, single sprocket freewheels...

Nice, simplistic (to me) design, that's well engineered. 5754 euro https://www.pony4.bike/drawings/ worth a drool over at least. Think others may have different takes.

Metal cut. Sorted drawing and dimensions. Wanted a safe set of accurate steering heads out of EN16 (tough stuff!!)

Sad news, just started following the great man. Just learnt that he lost his fight with cancer. I take my hat off to him, RIP.

Yes, don't tell H&S.... Love it, don't try this at home etc.

So, 2 trikes. Why. Well, 2 types of wheel configurations. Yes, I know that there are offshoots from these, but I don't want too much fog yet. They are my learning vehicles, literally! Fuel prices are going up, my car insurance company wants double what I paid previously. Fuel prices up 30%...
