I Need Power - Whats The Best

[Easy Rider]

Here's the place I usually buy my stuff from...and yes, those are the correct prices! LOL
Also I know BZM came out with an air-cooled 50cc head kit.

Andrew,
At this stage the only real spec's we have agreed on is that the bikes must be fitted with pedals. It is felt that there would be several categories including kw limited groups and bike set-up ie; mountain bike, sprinter, enduro etc. There would be a need for an open section where all goes but again must have pedals and be capable of being ridden. The distinction must be obvious between bicycle and motor bike. Commercialy the racing electric bicycle looks like a dirt motorbike more than a bike and this seems to be blurring the edges in my opinion. I expect the sport to develop itself fairly quickly as it is lots of fun and will attract alot of creative thinkers.
It is exciting to be talking of such a concept with the expectation of watching it grow into a reality.

Easy Rider,

I checked the link at didnt laugh at the prices - a bit scary at first. However in the cycling world spending 5 or 6k on a bike is only average. I noticed the engine is water cooled - another complication if using such a motor but and i can say the thought of riding a bike with that sort of grunt is very appealing and the obstacles will fade against the desire. The electrical bike suppliers are now discussing the 3.0kw motor mounted on a mountain bike with huge batteries and a 2.5 hour charger. The bike would have a top end over 100km/hr (hmm bit dangerous for me) but they believe the most impresive result will be the torque. Capable travel distance would be 60km.
Wouldnt it be interesting to see races between electric and petrol - i am getting excited at the thought (i prefer the sound of petrol but the lack of fumes with electric).

Hi Mike,

Given the loose set of rules thus far I would stick by my initial plan....get a dirt bike and rig a rudimentary set of pedals to it.....After you win the first race with this "secret" weapon, I'm sure rules would be made to outlaw this idea but at least you'd have 1 win under your belt! ;-)

I was thinking of trying to organize a motorized bike race here in Charlottesville (but haven't since I am so busy with my regular work) and thought of imposing weight restrictions of say 60 LBS or so....that would serve to eliminate ideas of taking a motorcycle and installing pedals on it (this would also effectively eliminate the Lifan idea unless an ultra light bike could be made since I believe the Lifan itself weighed something like 40 or so LBS ....I also thought of a stipulation that the same machine be human powered only for a certain distance race distance as well maybe 10 miles or so.....that would help ensure the bicycle aspect of the motorized bike remain intact (it'd be really difficult to pedal the ol YZ 250 that distance under human power....much less at fast speeds.

The other thought I had was to determine a distance to be raced and allot only a certain amount of fuel to be used.....That way if you run out (as in using a big engine) you'd have to pedal your machine....This would balance power, with economy, with making sure you can pedal your machine....

Oh well, just my random thoughts.....all kinds of rules could be made just have to agree
what rules would be good....

I believe racing would be fun and would definitely push motor biking technology ahead BUT, all in all, before we can race reasonably, I think a good set of rules and regulations would need to be made FIRST to help shape the racing machine itself...otherwise we'd be back to simply putting pedals on YZ 250's and Ninjas....

Hope this helps....if you do the YZ 250 idea we should split first prize! HA ;-)

hey mike... i totally support your idea of creating more power on motored bikes... all it requires is a little creative thinking and some people dont have that, but it seems that you are capable of thinking outside the box when it comes to horse power... listen to easy rider he knows alot and has helped me alot with carb mods and pipe mods! go get em and let me know of some ideas you come up with, im very interested in what you have in mind!!

I'm going to check if this head will fit on our chinese motors.

Andy - i love the way you think - share first prize.

Also as the racing hasnt started yet and my company will be giving birth to the sport here the rules as yet havent been defined but i am taking all your (and other peoples) suggestions into account to help formulate the best possible approach.
We intend to purchase several bikes and stage races amongst just a few riders at the moment to get the interest started in the sport - there will also be free riding lessons for the general public and hopefully they will respond. We will also be selling bikes to interested people following this and other paraphenalia with the aim of getting the sport up and running across all Australian states. Then we will be looking to set up in America and Europe (we will have specialised racing bike sales to all these areas set up very soon) and we will look forward to getting racing comps going globally - it will be very exciting - i just love shredding the dirt with my bike an i know anybody else who rides gets the same bug.
We are very close to confirming a manufacturing and development partnership with a very smart company in Asia (not China) who make electric motors and they have some awesome gear that is very scary - i love it.
So keep the ideas flowing - cheers.

Ultimusmaximus,

More power to you.
I am looking to make a pig using a petrol powered motor and a high strength frame with drum brakes etc. It should be looking at 15kw - it will definately grow smiles. No good for the road but wow easier to move around than a a dirt bike (no need for a trailer just a traditional bike carrier) and more fun.
The electric version should give wheel stand torque (single speed auto) but wont cost anymore and this can have a speed limiter fitted very easily with the potential option for road and performance mode? Hypothetically you could ride it to your favorite place and then go wild for a while - then ride it home legally - we will be working on this with the authorities. The concept will require the rider to physically dismount and remove a locking device to allow for power to be delivered to the motor. That same device would then also need to be locked. If the police think your speeding or other they can easily determine what mode the bike is in as the riser wouldnt really have the chance to change it. The bike would also have an on board power management system which would work as a data logger and contain power/speed level histories so the cops could prove if you were being a fool - this is the concept at the moment and hopefully we can have the best of both worlds? Also if a rider has a wild streak and owns this type of set-up he is more likely to refrain from going wild until he is in the right place as he has the option - after all cars do well over the speed limit but we control ourselves until we get to a suitable road system that allows higher speed.
I am looking for any performance ideas and tips as i have a lot to learn. I am a mechanical engineer and work at hypothetical design all day - but the real end of the stick i dont have any skill.

Easy Rider,

That is fantastic news and thanks for the heads up.
I realise it is not the same standard but skyhawk have a super rat motor - 80cc with a ported/polished head, higher compression and a biger carby - there is also a specialised poo poo pipe or racing pipe - it might be worth looking into?

Hi Mike,

I have heard of and seen pics of the super rat motor and racing pipe....are those available in Australia?....How much do they go for?....I would love to have one!
