well.. drive on a highway in Austria.. there is everywere 100km/h max. or 130km/h max.. nevertheless when i drive home with my VW Polo (which rarley runs 150km/h) iam all the time overtaken by other cars... some running 180km/h and more nearly nobody running only 130km/h then go to swiss...

well - "officially" its even not allowed to go with a normal bicycle through woods which do not belong to you.. (you can hurt yourself, and the owner of the woods can be liable for that) but thats a law nobody cares about.. the same with bikes.. when i go with a loud, noisy ICE-bike ruining...

@flecc: :D for the pic with the two trailers: you need a third one at the end: http://www.thunderstruck-ev.com/ibex_full_side.jpg there is somewhere on the net a small trailer, looking like the one in the first post of the thread-starter. but no soft-bags, but hard shell a hub-motor...

?? there is no legal way for you to drive the bikes ? unless i stay of the official streets - where is the problem ? i mean: on my own ground at home (2 woods, some meadows around the house) the police can say nothing... the problem is: i would not want to drive when i know, that my...

hmm.. in Austria we are allowed to go 25km/h (in the city thats fast enough in my opinion) so on a hill speed should not fall much under lets say 18km/h, otherwise the efficience drops into the cellar gearing: i also think: 2 gears would be enough (one for flat/tiny hills, one for medium...

hmm.. is that realy so expensive ? a highend biketec flyer F8 costs also 3750 Euro ! and thats a bike with 250Watt Motor.. an Optibike rated 400-600Watt costs between 5500 and 8000 US$ a Sweezbee costs around 3200 Euro with 240Watt rated motor so: if you want something special, it would...

hope iam not to annoying/cumbrous/importunate...

hmm.. i see question: inwheel-hub-motor it goes 25mph at flat and full throttle now there is a hill, a very steep hill i still have full throttle but of course 25mph are not possible anymore.. let say the hill is REALY steep, so the bike slows down to 10mph at full throttle.. that must be...

@Penguin: hmm.. sounds not that good (noise) i know now, that i have bought the 12V (so, old) version its currently shipped to me, so on its way nevertheless: i think 112 Euro is not that bad.. (have to considere that i get a 5speed-gear with it ;) , so the electric drive for that is...

yes.. the big benefit for ebikes is that we can use it on bike-ways... and here in vienna we have a lot of bike-ways ! for sure it shows us what is possible.. heavy: well, its lighter than a ICE-competitor in this class

well.. comparing to a car i think would not work on this.. you also don´t have to change gears from 0-25mph on a car.. nevertheless bikes do profit from changing gears on a steep hill when motorpower is limited... three ways: 1.) change gearing, so motor can spin still efficient also when...

well.. this as an onroad-version (should come this year) would be a great inner-city-bike i think.. 4sec to go from 0-30mph topspeed at 40mph for the update: the 16.8Ah 48Volt battery is now replaced by an LiIon 50Ah and 60Volt battery has anybody driven a Blade sofar in...

interesting discussion.. for "road e-bike" and efficient.. for me, this looks very efficient (roll restistance, aerodynamic drag, light weight, motor uses the bikes gearing, ...) battery: 24Volt and 6,5Ah with lipos maybe you can increase that to 36Volt at same capacity.. frame would have...

if it is 10s2p (so 20cells) or 10s1p (so 10cells) is unimportant for balancing.. (you connect first the cells in parallel, and than you would connect this ten 1s2p packs in series) the cells which are parallel are never unbalanced.. they are equalizing - if you want to say that -...

charging is not more difficult on a 10s2p pack than on a 10s1p the electronics (Balancer, Equalizer, or other names how it is called, electronics to ensure no cells is over charged and/or overdischarged, so single cell-monitoring) needs only to see the s-cells.. the single cells have to be...

well.. maybe not true for everyone.. ;) some want light battery and are willing for that to charge every day i just wanted to show, that also a small, light battery will not suffer power at all.. the bigger the battery, the more power it can deliver.. so "problems on hills because of weak...

@John: your first link -> 300mA max. dischargecurrent.. for a bike you would need more like 30000mA max. dischargecurrent (or more) your second link -> i doubt that this cells are high-current cells, they say something like "phonebatteries" here a picture of high-current-lipo-cells which...

@coops: "taking your trehad a bit off-topic" don´t see it that way.. is very interesting i hope now that it is the new sparc... (most likely will not happen) the new one seems to be lot better.. quieter, more power, more rigid however: i think the worst mistake i made: i looked into...

i see.. a powerfull bike (500Watt+ hub-motor for example) will on the other side weight a lot.. often 7kg for batteries, 4kg for hub motors --> that are over 10kg added.. the sparc weights only 2450g, + the throttle and some cables.. let say: 3kg (- 1kg for a normal 5speed-hub without...

@flecc: you have edited your post so new question come to my mind.. so far i have only driven/tested e-bikes in complete flat area ;( :rolleyes: the real interesting part would be on hills/slopes.. when i considere: pedaling with 100Watt --> can do that all day long pedaling wiht...
