Re: Hypothetical design

The velo-tilt ticks several boxes but isnt tadpole. Someone in USA has bought the entire project and is planning to produce them.

Re: Numb toes!

The numbness of toes I got riding recumbent on longer rides has reduced over time to a point where it isnt a problem any more. I suppose my body has adapted. I would be surprised if its footwear related. My vote is its the feet being higher affecting the circulation. Can you adjust the angle/height of the seat to see what effect that has?

Re: Air suspension recommendations

just checking but are you are aware that you can adjust the spring preload on most coil shocks to make them stiffer when you need to carry more weight?

Re: Unsuspended Highracer vs DF

Agreed there about the speed of hitting rough road making a difference . It can be a bit rattling on rough surfaces. Yes a Df rider can skip over a bump like a mini bunny hop and maintain momentum where a rigid highracer cant and gets slowed down by it. Would be great if there was a way to make a recumbent hop over pot holes.

Re: Unsuspended Highracer vs DF

I was thinking about that today on a ride. My weight is spread over a very large area from ass to shoulders so though I feel bumps they dont hurt. The weight of my legs is held by clipless pedals. Also Im not static and locked in on the bike and with experience there are ways to absorb bumps a bit. For going over steep speed bumps at pace (trafic calming type obstacles) with superman type bars I can sit up on my ass leaning forward and the frame flexes with the hit and seems to make it an easier stress on the wheels. This is with 28mm tyres on 26" wheels at 80 psi with a fibreglass seat and 2 layers of camping foam and no suspension steel stick bike frame. The recumbent is always going to be the one to ride on for any distance on roads. Suspension is just luxury well worth considering depending on what your priorities are.
Ive been riding them for about 3 years now and really the comparison I read once that it was like getting hit in the back with a chair is wrong. The falling back on a bed analogy makes more sense,

Re: Highracers - any experiences or advice ?

Better pics of the scopa. Its an amazing bike at a good price. Got some 10k local Kom s on it in the summer (about 15 mins) The major advantage that i can see vs a bachetta is that the seat position is fixed and it has an adjustabe boom. About £1100 total using a new frame and a mix of new and second hand parts. The wheels are 26" and the forks are off ali express meant for 24" wheels but work well with the 26" wheels and 28mm tyres. Larger tyres wouldnt work but it does have about 4mm clearance like this.

Re: Highracers - any experiences or advice ?

+ 1 for the scopa. It doesnt tick the hamster bar set up box. These bars do have a couple of advantages. Easier to sit up when stopped at lights. Sightly better underarm ventilation in summer or when riding with gusto. This pic is taken before i trimmed the fork steerer tube extender height and cables to corect length or fitted front disk. The scopa is available with a seperable frame and comes with modern tapered type headtube too I heard. Make sure you specify which rear hub frame spacing you need when ordering.

With 26" wheels its very easy for 175cm person to reach the floor when stopped. Didnt Dave macraw disprove the idea that stick bikes had a more eficient drive train than euro bend.

Having disk brake at least up front is something you should add to a list of wants
These bikes are capable of high speed.

Have You considered a goal X? I comunicated with a guy in Netherands and it looks alot better than the images on performers own web site.

He had eliminated an idler by making a bracket to raise the front of the seat resulting in a more laid back position and better chain line relative to the suspension pivot too. My current view is that suspension is a big advantage on a recumbent. Its just more relaxing not having to look out for all the bumps and holes and makes control easier.
Consider getting 28mm tubeless tyres and suitable wide tubeless rims from new . Dont worry about weight too much it makes very little difference to speed. Get twist grip gear shifters. Get a luggage rack and rear mud guard with your frame if available.

Re: 1x11 gearing on a bent

You probably went the right way with the double. My recumbent bike is set up with 44t single front ring and 11-40 - 10 speed cassette. After about a thousand K im finding id like a little more top speed (currently spinning franticaly to hit 60kmh) eg 48t or 50t. It would also be a better road bike if the gears had smaller gaps between them. But the simplicity of 1x is quite nice nice too. So a double would have suited me well and i might try it one day with a 11 -32 cassette but in the mean time maybe try a 46 tooth front ring.

Re: Down, not yet out.

Ive washed out badly with a kojac on the front (on an upright) I read in reviews online that they grip well but when they let go there is no warning. However ive washed out with other brands of tyres too so its not proof. It could have been a little gravel or moisture or like it was for me the road surface was very polished on the slightly off camber corner and there was no grip.

Challenge suspension explain?

Could someone who knows describe the design of the rear suspension of Challenge bikes like the Furai, Fujin or Sieran, please.
Ive been looking for ages and cant tell if the frame has a pivot built in to it or if its only the seat which has a pivot and is suspended and the main frame is one piece. I hope thats clear.
