Greg's Trike project

[Bikemad]

I will fix the tires directly on it, but now I must to find THE tire. I hope find an adaptable tires fixed directly on it.

Now I hope the Hub 500W 36 volts will climb enough slope.

Greg,

Here are a couple of links you might find useful:

P.S. Perhaps you could have modified one of these:

It would be cool that I can make one that looks like this (very beautiful and seems very powerful) but mine is better because the suspension system at seat will turn with the centrifugal force (hoping to get there)

How much does it?

Thank you for adress web, I will see store afternoon to buy medical tires, I don't prefer order the tires on web because if doesn't adaptable, I pust pay to return tires (internet) but I know now  12 inchs tires  exists with 2,8 cm rim size, it make me feel so good

How about one of these: http://www.edmond-wheelchair.com/wheelchair_pneu__tires2.htm
They have 9 x 2-3/4, should be close enough?

Good luck!

Helge,

Greg is hoping to fit the tyre directly to the HBS36F hub to give a small diameter wheel allowing maximum torque transfer for hill climbing.  It needs to be a solid (non-pneumatic) type as there is nowhere suitable for an air valve to be fitted in the hub, and I don't think making a hole in the tyre for a valve to poke through would be very safe.

Unfortunately the tyre diameter and the width of the inner section which normally fits into the rim, must both fit the hub flange instead.

I thought about fitting a solid tyre to the Magic Pie, which would be near enough a 16" wheel size, but the width available for the tyre to fit into is too narrow.

OK, I had overlooked that.
Even if a 9 x 2.5 solid tyre was found, I think it would be very difficult to install it without cutting down the flange on one side.

How about getting a 10" or 12" rim and weld or bolt it onto the motor, then it should also be possible to drill an angled hole for the valve.

If reverse is not required it might be better to use the mini motor and install a 10" rim with short spokes.

Helge,

The solid tyres seem quite stretchy. See tyre fitting video here

I'm not sure how easy it would be to fit such a small rim to the hub, welding aluminium is a specialist job, and magnets would have to be removed before welding and then refitted afterwards to prevent heat damage. (Not so simple)

Mini motor is not really suitable because regen and was specifically required by Greg for this disabled vehicle project.
(Presumably reverse will also be required)
See this post

I would like the tricycle can move at speeds of 14 km / h minimum (more if possible; D) so that it can follow me on bike)

With a 10" tyre, the mini motor would be much slower - approx 10.5km/h (6.5mph) max.  A larger rim would increase speed but the required hill climbing ability would be reduced. As Greg's girlfriend does not have the use of her legs, she cannot assist the motor on hills etc.

Maybe he should have got the PW-10S.

Model: PW-10S -- 10" Scooter Motor (brush/gear)
Built-in EMB Parking Brake
Manual Brake Release
Easy Replaceable Tire Design
Input Voltage: 24 VDC
Output Power: 300W
Weight: 7.7Kgs

I'm sure it could be overvolted to get more out of it.

Muzza.

Muzza,

The top speed is less than 9Km/h (5.5mph) with that one, so it definitely would need to be overvolted to get the required speed.
I wonder how much road shock would be absorbed by those tyres, I think the ride could be a bit bumpy.

Hi Alan!  
Thanks you for your help !

I have play my trike project, I think I will publish videos and photos when it will be finished (soon -about 2 month max depending when I will buy the expensive batery   ).

I managed to put 260 mm tire on the rim of the engine after having dug the tire a bit and cut the outer edge of the rim with a threaded rod to remove (which I kept for future times). I removed the tire so that now it is 300 mm in diameter lol.
To test I threw the engine ground and it bounces a lot. I break the motor garantee, I hope it will be ok and I regret they do not hub motor 36v 500W with good dimensions

i have try with tires and tubes but impossible (no exact )dimension and there is no possibility for valve (waste 18 €)
I hope it does not overheat to the point of melting the rubber because it is the only possible solution.
I finished the course that I built in aluminum and I rebuilt my fork.
I am currently at seat (many of welding).   
I get a foam chair old car for scrap.
I made the seat suspension from a suspended front fork of bicycle that I built with pivots for my girlfriend to look around corners.

The 4 wheel bearings are made with the bearings, which are the forks of the bike recovered Waste (iron scraps) is the same size as my rear wheels. The chance would have it:)
I am currently building the seat.

I have to do the handlebars (the sleeve is made with the walk up of an old child scooter lol it will be "design")
Painting
The battery housing and its attachments
Connect the controller to the motor controllers and mechanical brakes.

Any glue yet: D but it costs a lot of materials (iron, aluminum)


oups, now I i ask me why I have take the 36v 500w and not the 36v 750W
Could you tell me, Alan, what max speed it could go with 500W (rpm)and 750W, I can not read the motor performance curve

Thank you
Greg

Greg,

It's good to hear that things are progressing, and I'm looking forward to seeing some photos.

Could you tell me, Alan, what max speed it could go with 500W (rpm)and 750W, I can not read the motor performance curve

Maximum motor speed 36V  500W = 340rpm (19km/h with 300mm tyre)
Maximum motor speed 36V  750W = Unsure (I don't have any figures for this motor)
Maximum motor speed 48V 1000W = 470rpm (26km/h with 300mm tyre)

The golf trike motor    48V  750W = 390rpm (22km/h with 300mm tyre)

Alan
 

[Bikemad]

the 750W too only 18 Nm
golden motor say 18 NM at 266 rpm (508 w) but if I go less than 266 rpm (14km/h), the torque isn't more powerfull ?
because 0 to 5 km/h (0 to 98 rpm) with 18 Nm do it in 7,72 s !! it's too !
any idea ?
i don't want to buy two battery, two controllers, two motors.

Greg,

I don't know if the 36V regen controller can cope with the higher voltage, but a 48V boost would certainly help to increase the available torque, if only for short bursts when it was really needed:

Hi, I have finished the trike (the structure) it need the battery and wiring.

You can see it on my face book

Mods, I can't see facebook in china.

And for us "older" ones who aren't into facebook, can someone post a pic here!
