Re: Building a recumbent trike rear wheel

It only really matters if you're going to fit 50-406 tyres due to the back fork being wide enough to fit anything smaller even if slightly offset.

Re: Building a recumbent trike rear wheel

Won't the distance change between the lock nut and flange depending if it can fit a disk rotor or not ??
That probably account the variability in the 6mm measurement.
I do know m Rohloff has a reverse dish to cope with the frame offset.

Re: VTX Luggage

For things like just a puncture repair kit, I'd look at something like a top tube bag.
It will sit on the main tube just in front of the cruciform.
You may need add an extra strap to stop it rotating.

Hub dynamo and/or solar panel and/or mains charger plus a power bank or three used as cache batteries.
My Garmin is powered from my hub dynamo and my power bank is charged from a solar panel.
The power bank is then used to recharge my Kindle and any AA I've drained.
I like to wild camp where possible hence going the minimum power usage route of using a paper map and plotting the route by hand.
Therefore I can go for months without needing to recharge anything from the mains grid.
If you're using a phone to navigate then the normal trick is to charge one power bank off a hub dynamo while powering the phone off a second one.
Getting the odd charge from the mains as needed will keep you going.
The less power you generate and/or the more power hungry your devices are the more often you will need to find a mains power source.
It easily possible to charge a big expensive power bank in a campsites office every few days.
Or a small cheap one each night in the toilet block.
I've done both those tricks on the first couple of tours I did before I got my hub dynamo plus solar panel setup

Re: GPS Systems for Long-Distance Touring

I do something similar with my Etrex 30.
Route planner -> New route -> Use map.
This then lets me scroll across the map adding points roughly 2-10 miles apart along my next days route.
I then let the Garmin calculate a route between all these points.
I then need to double check there are no silly Sustrans like diversions between some of the points.
If there are then I delete the route and redo it with added points to fix the diversion.
With practice I can do the next days route in two attempts.
But it's something to do in the evening while I wait for my pasta to cook.

YMMV ........... :D

Re: GPS Systems for Long-Distance Touring

The other thing to take into account is exactly where you are aiming for, how long you've got and how you plan to get there.
Most of the main European river/canals had good sign posted route along them. I only need a satnav for the last few miles to a camp site or if I looped away from the one I following.
Eurovelo routes can be a bit more tricky. Some are well signposted, some can be signposted with only the local route name and some are missing large stretches of signposts.
Cutting across country to see interesting sites tend to be more about keep off busy main road. Then plotting the route into the satnav the night before can help you remember where to go when you reach a junction.
My main use of the satnav when on tour was to easily navigate myself out of a city or off a busy main road I got onto by mistake.
But I had no real goal other than being away from home for the summer, so I did alter my route and wander where I felt like it along the way.

Re: GPS Systems for Long-Distance Touring

That's basically how I toured and lot of it comes down to electrical power.
How much can you generate and how do you make up any short fall.
Do you use a large scale paper map or a phone/tablet with a preloaded map to forward plan any route changes, I used the paper map route.
Things like more power hungry your satnav device is, the less you have for other devices, phone vs satnav.
Little things like I run my Garmin off rechargeable AA but in an emergency I can run it off Duracell's.
Etc, etc, etc.

Re: Best Camping & Caravan Club sites for cycling

I like St Neots.
Most of the traffic is going directly N-S on the A1, so lots of quiet lanes to explore in rolling countryside to the E-W.
Plus a good café in the town centre.

Re: Cadence & Body Rocking Pedalling Fast

What speed is this happening at ??
On a slight uphill slope so the trike doesn't get away from you, try just resting both your palms on top of the handle bars.
With your hands just resting on the bars then your top half should be more relaxed and do you still rock your shoulder at a high cadence ??

I used to develop a slight rock at high speed due to feedback through the trike.
A trike reacts to a change in you CoG by moving away from it.
Lean right to counteract a camber and a trike automagically tries to turn left into the ditch.
This is not normally noticeable on a bent trike until you hit high speeds and the steering gets very light.
Then a slight rock in my hips due to over spinning set up a slight side to side snake like oscillation on the trike which fed back into a bigger shoulder movements.
Now I've ultra high gears on the trike, I no longer need to over spin to hit +30 mph.

Re: Anybody with a recumbent trike in Gloucestershire?

I tried riding a bike after my accident with a tiger and while it was possible, the safety factor it was also very iffy.
Found ICE on the internet and gave them a ring, "can I come and try one".
I was very 50-50 about buying one on the drive down.
It took me 30 seconds trying one around the carpark to decide "I WANT one of these".
Picked up my first bent trike a couple of weeks later.
That was ~12years ago.
It took me a further 4 years and a new model to slowly tweak the trike to it's current configuration.
Once I truly built up my bent legs, I never regretted it.

I now use a quick link to show if there's a twist or not.
The plate on the half that stays on the new chain is always on the inside.
If I don't use the old chain to pull the new chain through then I still put it on the start of the new chain as a visual guide.
I find that easier than using a bit of tape/thread around an outside plate as a visual guide.

Re: Disability issue - how to brake with just left hand

Being a left arm amputee I've looked into this.

The easiest is just to use a single brake and ignore the other. If you just use the back brake then you lack stopping power, it you just use the front brake then it dangerous in the wet due to the risk a front wheel skid.

The next option is to use a single lever to pull both brakes. It gives better stopping than a single brake but it's not road legal. Main downside is you cannot vary the stopping power between front and back as needed depending on road conditions.
You can improve this setup with a third brake worked off a friction lever. This makes it road legal plus you can use only back wheel braking in the wet.
This is very similar to how my bent trike is set up. Both front brakes are off one lever and on a trike it doesn't matter if a front wheel skids as I cannot fall off. The back brake is only used as a drag/parking brake and is worked off a friction lever.

After that it gets more tricky/expensive.
A single brake body with twin levers is possible.
Some type of fancy push lever on the weak side.
A back brake you can push on with your heel.
But you really need somewhere like a university to help built/test some of these options.

Re: Crazy mystery chirping screeching noise

If it started during a ride in the rain, then it sound like something small got washed into somewhere it shouldn't be.
As it still there while you are coasting then a wheel bearings or calliper may be the source of the noise.
Take the wheels off and spin the axles carefully be hand, what you're feeling for is a rough/sticky spot that maybe a sign of a bearing on the way out.
While the wheels are off, double check there's nothing stuck/trapped in the bottom of a calliper. Also have a good look at the rotors that there's not a worn line on one that may indicate that somethings rubbing on it.

Re: Anybody with a recumbent trike in Gloucestershire?

I you're going down the second hand route then try contacting Kevin Dunseath, of D-TEK in Little Thetford near Ely.
He's the person to get in contact with about all things second hand recumbent.

The bigger knee-hip-shoulder angle on a recumbent means you don't engage your glutes as much when you pedal, so you rely more on the quads for power.
So even if you're cycling fit, it helps to do around 1000 miles to build your quads up a new level of fitness and get your "bent legs".
I was very unfit when I first got my bent trike and spent many an hour over the few months in first gear cycling up the most gentle hills at around 3 mph wondering how to go faster before I built mine up.

Trikes can be "fun" on a camber.
If you lean right on a trike to counteract the camber then the trike tries to turn left into the ditch.
So if you're not careful on an upright trike with it's high CoG then you can find yourself automagically in the ditch.
This effect is much less noticeable on a bent trike with it low CoG, so nothing to worry about but it is how you can steer a bent trike hands off.

Re: Does any decent wired bike computer with average cadence exist?

You still need to input your gear size somewhere in equation even if its only chainring/sprocket.
I spinout at just over 90 rpm.
In my 9.4" first gear I'll be doing around 2.6 mph when I spin out.
But in my 179" top gear at the same cadence I'll be doing very close to 50 mph.
You must take the speed variable from the gears into account unless you're riding a fixie.
