http://www.engadget.com/2013/09/04/rima ... tric-bike/The idea of Greyp came to life when Zvonimir Sučić, a well-known designer of high-performance electric bicycles and motorcycles, joined Rimac Automobili as a mechanical engineer in 2010. Zvonimir developed and built electric bikes since 2001. in his garage with the help of a couple of friends as a hobby. His first production-bike, the Greyborg, was delivered to 27 countries but still remained an after-work hobby for Zvonimir. Mate Rimac liked Zvonimir's creations, but he didn't like the technology under the skin so he decided to design a bike after his standards and present the idea to Adriano – the man that designed the Concept_One. With the help od 6 Rimac Automobili engineers Zvonimir, Mate and Adriano started to design the first Greyp from ground up – this was the 12th bike in Zvonimir's bike- designer career. The G12.
You do realize that if you are worried about range going 50-60mph will only get you a few miles before the battery is dead... if things don't burn up first.mvly wrote:Tempting for a production solution. Great for people who do not want to mess with building one themselves. I am a bit skeptical about the range though. 120Km on 1.3Kw is pretty tough especially at 110lb bike. I would say you need double that to do it comfortably.
Wonder if we can upgrade it to a 50-60mph ebike down the road and how easy it would be to do so.
i don't know so much about this bike ,i was watching an online video and came across it,i still don't understand why it has 12kw with such a low speed ,but i think the speed setting could be changed because i can see a large kelly controller in there,also price range and features in comparison to the stealth electric bikes is very reasonable but i also want a larger kwh something like 2.5kwh as a minimum if i have to purchase a bike like that .jansevr wrote:wow! nice find, i had no idea a new one was even in development. maybe there wasn't any talk or leaked pictures until they had a relatively completed design. the features like the fingerprint activation seem a bit over the top but its still a cool idea and will definitely get it attention. im also happy to see that they have made their own battery module. for the size, 1.3kwh seems very reasonable! a bms is definitely a plus as well! the price seems a bit steep but in comparison to stealth, $8000 seems like a fair price especially considering the added features and more power from a cro motor!
i also just noticed that the voltage is only 64v (hence the relatively low top speed of 40mph). but for 12kw at that voltage that's over 180amps! seems like it would be rough on the battery...but they still claim a "minimum life of 3000 cycles while still maintaining 80% capacity." the batteries are a123, i was unaware that such high amp draw was possible from cells like these...maybe they are new/redesigned?
Great technology, consumer ready and all... but I have to admit Chalo's analogy is right.Looky, somebody put wheels on a saxophone case.
frock me Chalo, either say something nice for once or don't bother replying. Like you could do any better. Every post you make is filled with hate and negativity...this community thrives on encouragement and help.Chalo wrote:Looky, somebody put wheels on a saxophone case.
