Imho the electric motor on the front would be much, much simpler, no maintenance, no braking points

[@kasuraga]

@@west_adv you would add more weight and bulk doing that, since you'd also need a hefty sized battery pack to go along with it.

[@onecookieboy]

I agree with @agzrele, the parasitic power losses from all of those bevel drives, sliding shafts as well as the drive shaft to the front forks and chain must rob the engine of a lot of power, not to mention the maintenance aspect of it. Furthermore, the setup would add quite a lot of weight to the front of the bike, which is not ideal. We have a 2wd ebike here in New Zealand (mostly sold for farmers or hunters needing the extra traction in muddy conditions) and they report that having a driven front wheel makes the handling rather hard to manage, I imagine that this system would be even worse because it's purely mechanical so if the back wheel loses traction so does the front. It's an interesting engineering concept, but more of a novelty than anything. At least if you used a hub motor and battery, you could mount the battery in the rear, put a controller almost anywhere and the hub wouldn't add too much weight to the front, you could also have easily switchable power to the front with a easily built in traction control system.

[@theyeetus1428]

[@russshappard1059]

I bought one, spent thousands on it, rode it 3 times, sold it for a loss. At times it was great, in the mud and tight single track... I thought it was worse. Had to remember to make sure the front end was pointed exactly where you want to go, every time the front end comes back down or it will throw you into the bushes or over a cliff. Different kind of riding, like changing from 4 stroke to 2 stroke... you have to ride it differently.

[@RL-un3yq]

Interesting perspective. I would have thought in nearly all cases it would be better, minus added weight and maintenance. Guess it's one of those things, you don't know till you try it.

[@greengoat5654]

I'm not too surprised, most of your weight is on your rear wheel on a motorcycle anyways, and to be fair most of dirt bike riding is not being in control half the time so

In certain situations these bikes are amazing, dry days evens out the field and they are a lot heavier. But fun none the less. Biggest issue is keeping the front end and bearing happy. LOTS of parts that can fail. And a clutch to adjust that can be a bitch, too tight and you blow bearing in the front hub.. etc.

Around 20 years ago Yamaha had the 2-wheel-drive WR 450 F2-Trac. It’s a hydraulic system and gives up to 30% to the front wheel depending on the wheel spin/traction loss of the back wheel. But this system looks also pretty cool especially for a retro fit.

[@TheDirtbikeRider]

[@austinasbury5823]

The fact they just snuck in an awd hybrid dirt bike in the end was amazing. That looks like an incredible piece of technology.

[@spacee3249]

Fun thing I've seen, someone back in the day made a 2wd by adding a hydraulic motor - the rear chain essentially drives a hydraulic pump which then moves the front wheel when needed. He briefly mentioned hydraulic pumps in his video, but not how they worked in this respect - I'd say it's as simple as a front electric motor... Without needing electricity

[@WhiteOwlOnFire_XXX]

Yup Hydrolic is a much better design

[@DigitalJedi]

Hydraulic is definitely an interesting idea to drive the front wheel. With how powerful modern electric motors are and how efficient generators or even alternators can be though, I think going electric is a good move. Instant torque front and rear would be something else, and for a full electric setup would be as simple as dual hub motors.

[@ss67camaronut]

I'd heard of these years ago and believe there was military applications and that it was mainly being developed for that. I'd imagine electric motors now would trump this design if technology is here now for it. Would be just as fast , could be full time 2x2, and totaly stealthy as nearly silent compared to a gas engine. Battery weight likely the main issue, but the tech is growing very rapidly and I'm sure the military is on the cusp of it if anyone is. Enjoyed the video 👍👍👍

This is definitely a new take on 2WD bikes. I had a Rokon TrailBreaker back in the mid 1970"s. Rokon's are not "dirt' bikes though. They are slow and steady trail bikes for going where there is not a path. I think that they will go places the Christini will not, but the Christini is light years faster. The drive system was very different, too. The 2WD is full time and only cuts out on the front when the spring loaded clutch slips (by design). This seem very cool, and I wish it had been around when I was an active dirt biker, 30 years ago. LOL

[@wazzanose]

I tested the Yamaha 2-Trac for Australasian Dirt Bike Magazine, and the story was re-printed in one of the US mags as well. I liked it, but many of the top riders that rode it didn't. I think this may have been because it tracked so well in slippery corners rather than sliding. They were all used to steering with the throttle and back wheel in those conditions. Only 250 were made, and only 20 came to Australia, none went to the US. At least one of the Aussie 2-Tracs was sold by a dealer here to somebody in the USA. They couldn't be road registered in Austrlia as they did not have a compliance plate and were twice the price of a conventional WR450. They also came with top of the line Ohlins suspension front and rear and an Ohlins steering damper.

Both of which will make if feel heavier then 6kg (more like 10-15 kg) and dramatically effect handling. I also wonder what effect the two drive shafts have spinning adjacent to the engine and having a torque effect on the steering would do to over all handling? All that being said bike set up is a game of give and take to improve in one area you usually have to give up in another area and for all the negatives I’ve mentioned you are gaining traction which in some circumstances is very hard to come by😀 Hopefully one day i get to try it out

2 of my 3 electric bikes are All Wheel Drive. Its 2 independent system. 2 Motors, 2 controllers, 2 batteries, displays, 2 accelerators, one for each thumb. I also have 3 motors on one my bike which is 3 everything. 2 thumb-throttle on the right and one on the left. The 2 on the right are the rear hub motor and the mid-drive motor and the one on the left it's the front motor. I used many combination. The thing with all wheel drive is the front wheel is directional. So at low speed when you are turning for example you want to be careful and use very little throttle on the front motor because the bike will pull the bike this way and you will go the other way. So basically when I turn at low speed, I only use the rear motor and when I get more straight I add the front motor. At least in the beginning when you learn and you are not used to it. Note that my experience is on the road and snow. Off road folks have more skill will probably get that in seconds. Humbly!

I drove it both on flat track dirt type roads, as well as, of course, difficult terrain, mud, Sand and rock. Going down hills I didn’t even have to worry about locking up the rear tire. I would just squeeze the front brake and the thing would stop. The front tire was driven by the rear tire so that it was very difficult while going downhill to lock up the front tire. While going uphill on steep terrain, I would just lean as far forward and that coupled with the torque 572 and automatic clutch, would creep up any hill at a very low speed very easily. it did add a little weight but I just adapted and it was fine. I removed the cooling fan on the radiator and ran a different coolant that boiled and a much higher temperature so that I could have room for a 3 and a half gallon gas tank. I ran a lot of long trips through the mountains and deserts and needed the extra fuel cap capacity. Christini provided the fuel tank too. Maintenance was simple. Keep the moving parts greased and everything was happy. I stripped the frame to bare myself and sent it to them, got it back in a month,and put It back together myself.

It's got a one way clutch in the front wheel. It doesn't hold back..

I've been wanting one of these for about 15-years now. Now, I do not live in a location that can really use it anymore.

[@RocksNRuts4]

im impressed! clean design those small hubs r sweet. figure he would get million dollr offers frm big names but i guess haters dont like it.....solid patten to not b stolen already

[@caddy8436]

Wondering how it would do in the Dakar race?

[@johnsanchez6263]

Wow they really did it

[@deltabluesdavidraye]

To be honest a low wattage electric hub motor built into the front wheel would be simpler and only the synchronization issues would have to be sorted out.You don't need much power to have a positive effect.

[@wyattcitizenzap4539]

that is the most genius thing ive ever seen.

2 stroke awd… dreams can come true.
