    Three-wheelers. Trikes & Velomobiles

    Good words there. Frames like this which I've nearly finished for a Greenspeed Aero trike. I may use this fairing as it is, covered in polyester heat shrink, or nylon and dope, then use that to make a quick mould to produce a carbon fairing, current weight 850 grams. Been running with the...

    Three-wheelers. Trikes & Velomobiles

    This YouTube vid has probably been seen by 'AZ' peps already, but worth a post I think.

    Support for Warrior Trike

    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...

    Trike fairing. Wooden?

    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.

    Trike fairing. Wooden?

    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...

    Trike fairing. Wooden?

    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...

    WC2024 - World HPV Championships - a folly to far ?

    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...

    Trike fairing. Wooden?

    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...

    Trike fairing. Wooden?

    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...

    Front wheel drive at the hub. No chain.

    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...

    WC2024 - World HPV Championships - a folly to far ?

    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!

    Miracles!?

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

    Interesting 4 wheeler

    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!!)

    RIP Mike Burrows

    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.
