Trike wheels

Hello Gentlemen,

I have just finished my first DIY trikeand it really looks good.
I have a few problems however, but as this was my PROTOTYPE I don't mind.
Here are a few remarks and I'd like to know if someone could give me a reason:
1° I think that I have to put a lot of leg power to advance the trike. Once it is rolling all is O.K. but to go from 0 to a certain speed, it is really harder than with an ordinary bicycle. Is that normal?? The rike weighs 24 kg or +/- 49 pounds.
2° I have a brake only on the back wheel and it is just a simple one, not a disc brake. And the braking is really not effective. Maybe with new little brake pads?

But the question I have in mind is for my REAL TRIKE, the Warrior.
The original design is with3 disc brakes. And to be honnest those front wheels with big (14 mm) axels and a disc brake possibility are here around 95 dollars each. My question is now, could it be that using only a disc brake on the rear wheel, there will be enough brake capacity?

Another question is : where do you guys find those wheels with disc brake possibilities and at what price? Maybe I can order them in the UK or in the USA or even in China, no?

Thanks for any kind of answer. And... in the next blog I will add a few photographs of my Prototype Recumbent bike.

Cheers,

Charles

If it is hard to "set-off" then your initial (low) gear is too high or there is "friction" in your drive-train perhaps.
What front/rear sprocket combination is it you are using when you pull away from rest.

I can't answer the "how to get cheap disc rotor capable hubs & rims" sorry, it depends what you can find in the scrapyard and whether you are willing to build your own wheels.

Pictures are always appreciated.

I have seen a lot of first time trikes projects use a very bad drive chain guide, and that can be a huge amount of friction.
Some bad chain guides... skateboard wheels, brass bushing (non ball bearing) pulleys, any pulley less than 3" in diameter.

Yup, photos tell the whole story!

Hi Charles

DO NOT RIDE A TADPOLE WITHOUT FRONT BRAKES Its Dangerous .

We have used recycled "quando" MTB disc hubs (steel with the large centres ) and replaced the 10mm axle with 14mm BMX spindles and 3/16 balls . These work well and I have converted several to use with 14mm axles and 36h rims .

Cost wise we have paid as little as a couple of GBP for a BMX wheel and the same for a scrap MTB wheel - for under a tenner we have built a set of disc wheels ( recycled spokes and rims )

Hi Charles
Tadpole trikes have significant mass transfer to the front wheels under braking. To put it another way, the harder you brake, the less grip you will have at the back wheel. I only use a rear wheel brake {caliper} as a parking brake, but for load carrying or speed runs, a disc brake forstopping would be a good idea.
You can make yor own hubs, spoke flanges and disk brake adaptors easily enough. Mine consist of a tube machined each end to take a bearing, a spoke flange disc welded to each end, and a disc brake adaptor screwed to the end of the tube and through the spoke flange. You will need access to someone with a lathe.
In Australia, we have organisations called Mens' Sheds {sexist term I know, but women are allowed as well}. They exist for the health and wellbeing of people who, through life circumstances would otherwise be on their own. They have well equipped workshops, cheap membership, and you can make almost anything you want or use the skills of others. This sort of access allows you to re-use rims and spokes which is much cheaper. If there are no similar organisations in your neck of the woods, there should be.

yes you can build your own hubs but finding 14mm wheels can't be that hard. look for BMX wheels, they usually have 14mm axles. I myself am going to build some 20mm axled wheels. Will take lots of pics
as for brakes, yes front brakes. caliper type rim brakes work good as do disc brakes.
