After developed some leaning motor scooter types,I build the kit recently,the kit can be applied to most 20"~26" typical bicycle fine without damage the bike frame,just disassemble the fork and replace the kit frame through head tube on the bike

hodala

The work actually build by a mechanic in China never met before,with remote control build step by step through e mails

The third illustration picture without leaning function is much simple and easier to do,the type is for one who is not able to ride a bike

I like it.

Independent front suspension that leans A LOT. Does it require the rider to keep it upright, or is it somehow rapid acting auto levelling?

I would encourage you to evaluate adding some Kingpin Inclination. It should help brake steering A LOT. Are the front brakes tied together? Still, as as safety issue, brake steering is bad.

I think you can also adjust camber and castor to naturally tilt the bike a little on corners.

The sus. arms react like seesaw with each other left & right,so you can't say "Independent", it's called full floating suspension,without power assistance,leaning and steering independent just like a 2 whees bike

the sus. linkage all parallel no need king pin inclination for leaning bikes should be also fine,brake also no ploblem

Yes; caster is adjustable;the bicycle kit basic dimension almost the same as motor ones but lighter the tube and plates

CliffordK

It sounds like fun.

With a vertical kingpin, apply the brakes, and it turns the wheel hard to the side where the brake was applied.

With an inclined kingping (pointing approximately to the center of the wheel), apply the brakes, and the steering doesn't pull.

A linked brake system will help. But say you break one brake cable, then the bike becomes dangerous to ride. And if the fault occurs unexpectedly, then rider reactions are hard to predict, and it could cause a crash.

Don't understand why the brake bother you so much,I'd ridden the scooter BWs 100cc trike,the scrub 54mm off road ride won't cause any problem at all,although bicycle scrub 78mm bigger than scooters,slower speed and less weight cause much less the scrub torque on your hands

Hey hodala, would you mind saying what the original bike was that you modified. It looks very cool on its own and I don't think I have seen anything like it over here.

hodala

There are some of modified models,the scooter I ride is BWs 100cc;Chinese fake grom, 3&4 wheelers whole build fat bike

sarahbruce

Oh I was actually asking about the pedal bike in your first pics!
Thanks,
Bruce

hodala

Let me show you why I didn't incline the king pin to reduce the scrub,a good design should compromise all specs and cost to achieve the best benefits

Also see a type with half the wheel span scrub,full floating sus. can release road resistance a lot

hodala

As I mentioned,most bike will be fine to modify, the red one is a local cheap bike in China,fat tire bike model

sarahbruce

Huh.... Do you know what the brand name is? I just haven't seen a 20" wheeled fat bike with gears and disc brakes over here in the US. The middle white one looks similar/the same as the red one you posted first, but I still can't tell what brand it is. I was just wondering if a similar bike could be found over here.
Bruce

hodala

I checked the brand is "QUISKI",most fat tire models 20" equipped with gears and disk brake in China web market 淘宝,
if you can see the model in "Alibaba",may be some distributor would import the bike

fietsbob

Weight conscious group here... How many Kg is that?

hodala

You've got the point,weight is the disadvantage of the trike,the trike weights 28kg now with the basket, too heavy of mild ion plates and tubes,I'll try to lose some weight of the kit,but the cheap fat bike also a little heavier too,if the bike weights 14kg, say a common 26" mountain bike,the whole trike(with basket) 25kg should be OK,and equipped with e motor assist should be better

These 2 danish leaning trike are known to the public

hodala

I was supposed to modify my 20 years 26" MTB during Chinese lunar new year vacation start today, but the international freight stopped delivery and postpone for 10 days,so the front end kit not available,I have to wait until then

The last picture is an integrate frame style

hodala

There is a Japanese basic cute little trike

hodala

Versatile bike- safer off road riding,shopping,carrying kids stroll along- -can I say:enduro utility bike?

First ride my 20 years bike conversion today

hodala

Bought some food from traditional market this afternoon

hodala

These prototypes were the cargo bikes I developed for EU distributor shipped to Germany last December


I'm now building G2 front end kit of my own for local market
This is exactly for bicycle geometry instead of lite kit G1 from motorcycle
