Beema is a inner city trick bike by Andreas Martin that allows you to take on any obstacle that the urban area throws up; chairs, banks, rails or just the street. It fills the gap between FMX, scooter and BMX. Besides the the stunt riding it gives you the possibility to overcome distance inside a city by having two kinds of driving modes, the stunt-riding mode of course, and then the cruise mode that seats you in a more relaxed position. The project was done in cooperation with BMW Motorcycles see the whole process here.

Pretty cool design, but I’m not sure how the front suspension works. Looks like the front fork pivots towards the bike which wouldn’t really be what you want if you hit a bump when you’re turning. Looks like it was set up to take loads from the rider, but not the road, which is what the suspension is for.
DO want.
Ok I cant tell from the pictures here if this is human powerd, electic or wombat but I see some real problems. The biggest is weight, unless this is built of unobtainium and fairy dust its going to weigh a LOT, and if you ever noticed bikes tend to be the other way around, you know light as possiable. That syle of rear suspension causes a lot of pogoing (where the power pulse compreses the rear suspension and there by wasting power) on a human powerd cycle, thats why you only see on gas power rigs. The front suspension just baffles me, I have not a clue on how it can work. In the end, I cant see this being workable a case of a little knowlage and a lot of time on the tablet.
At least he’s proposing some new and interesting ideas for thought. It’s a concept design. Don’t rag on it. You people are good at whipping up criticism but you have no idea of the design process. You’re looking through engineers eyes with blinkers on. Try to get some imagination and creativity. This is top stuff! I love it.
dont pointlessly defend an idea, so what if it looks cool and interesting? if it doesnt work in real life its useless! nice rendering and nice concept but spend a litle time on the egineering aspect!
Right, and also where is that babe supposed to put her feet?. It just doesn’t look like it’s nimble enough or ergonomic enough to zip through busy city streets, let alone do stunts on. At least not any kind of stunts I’ve ever seen. Looks more like Apocalypse Bike.
OK. Didn’t see the link. Interesting. Hope it’s more successful than their skateboarding catastrophe.

still unclear if its internal combustion, electric, human or wombat powerd. If electic, human or wombat its way way too heavy.
to my knowledge its electric driven. volume doesn’t imply weight, biger profiles just ad rigidity they don’t necessarily need to be filled. new electric motors are extreme powerfull and take less space than their combustion counterparts the only thing that realy is a problem is the electricity container (a.k.a. battery)
a carbon fibre structure filled with foam and mounting points and retainers for bearings laminated into is not that heavy, lithium batteries are acceptable and a motor housing made of a titanium magnesium alloy will be fethery, declared that will make it expensive
i can’t tell how heavy (or light) the bike is and i wonder how you can.
Ok if it is electric, then what is there is not so horrific, but any volume adds weight so it will have a impact on perfomance. I am assuming (hate to do that) the the “tank” is the area for battery storage and if LI shouldnt upset the balance too much. The real problem now is the front suspension, unless there is a trailing arm stytem burried in the front fork body work its going to be a real weird ride. The rendering of the suspension working is unclear, to my eye (having designed 5 bikes and 3 recumbents) that the head angle will change with suspension deflection, this is a real no no generaly as it will radilcly affect the handling. If it IS elelctirc, and if it has decent perfomance (range/speed) and has a rational price then this could be a winner.
I see potential in this design, in 3 ways. The reason i say that there is potential is that i live in a congested city but i ride downhill mountain bikes. The stability of the bike coupled with its good handling characteristics allows me to reach a given destination no matter what the terrian in a very very short space of time. But what this addrsses is the “going-up” factor, if indeed it is mechnically powered, which if anyone has ever ridden a downhill bike will admit is not easy going. And you don’t have to lock her up:)
There are alot of problems with the design on face value. The first being that overall weight. Suitable powerplant, although intergrating the power plant into the structure of the bike does save weight. Conventional forks always work better, are lighter and easier to sevice and more maintainence free then intergrated ones. Another thing is the pivot placement and high centre of gravity of the bike. I design dh mtb’s and any rider will tell you a high single pivot, top heavy bike can be a really handful in a tight situation at low speed.
Hope you guys get it sorted, coz riding urban dh style ROCKS!!!
Hi!
I`m from Brazil, i study mechanical engenier in PUCRS.
I`m interisting in yor bike.
I`m like bike and motorbike.
Do you sell this bike? How much?
Sorry, i don`t espeak english well.

pegs are fail, and you’d want actual forks , not rigids if you’re going to be hucking off anything bigger than a kerb
DO you BMX?
I do think that this is very bulky and would be considerably heavy, altho i would still buy one as it is incredibly awesome!!
I just wont to know where to get one!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
