    There appears to be a new genre of pedal-bike coming out. The Bultaco Brinco and the Stealth Bikes Silent Bomber are two light-ish and almost-light (well, lighter than most motorcycles) pedal bikes that have a serious electric heart.

    It's conceivable you could turn the electric end off, and pedal on bike trails. Or get on a major road and merge into traffic, perhaps even on some highways.

    Are there many other bikes like this out there? Many more on the horizon? They're expensive now but if they get a little cheaper they'd be a lovely option to have.

    edit: I'm looking for bikes in around the 30kg range or less. Should be able to motor at above 60km/h for at least 20 minutes. Be engineered from the ground up (rather than battery+motor strapped to dedicated pedal bike) to handle these kinds of situations, so fully suspended. Basically I'm looking for something that can do a day-to-day 20-30km commute, on roads with varying quantities of cars and speeds. Something where you can keep up with traffic even if it's going at above normal pedal-bike speeds.

    That looks like a pedal bicycle with some strapped-on batteries and motor. I suppose I'm looking more for a properly-engineered bike. If you're going to go up to 60kph for sustained periods of time I'd imagine that frame wouldn't handle it (resonance issues)... But perhaps I'm wrong. Have you tried taking that bike up to ridiculous speeds on a variety of surfaces, and how stable is it?

    For example, here is the Brinco:

    4,800€??

    Is that a joke?

    I'd be more interested in a proper bicycle with an electric assist, like the earlier pic. Add-on tech would be far less expensive, I would think.

    many of these are just bionix battery/electronics components strapped onto a bike with a hub motor in front or back. Go to NYCeWheels.com or something like that to shop around at what's actually being put on streets for commuting in NYC. They've got some pretty cool component-built options. And then they've got some dedicated engineered e-bikes. Stromer seems to be an awesome option to me.

    But I think most people here would go for the Haibike lineup.

    Sure it's expensive but it's early technology. People said the same about lasers, HID lights and LED lights. It's purpose-built, so it has different capabilities. I'd like this discussion to stick to the topic rather than be a complaint thread.

    Thanks DriveShaft. I hadn't found a central source where the main varieties are available. Browsing your suggested page now.

    These seem to be all electronically capped around 27-28mph. I'm fine if the bicycle is legally a motorcycle. Probably would prefer that for commuting purposes. Are there any other "legally a motorcycle" electric pedal-bikes out there?

    For myself, I've been toying with the idea of doing a e-bike conversion on my Big Dummy frame, putting it into contention as a daily commuter against my scooters/motorcycles. It'd probably be a bionx setup like this:

    [​IMG]

    Except I have to choose between nixing my rohloff hub or my front dynamo hub. Not an easy choice. :lol3

    A couple people have done it before, so it'd be a relatively easy to figure out deets. http://www.practicalcycle.com/customers/electric-bikes/142-surly-big-dummy-goes-bionx

    http://www.specialized.com/us/en/bikes/ebike/turbo

    When the Turbo was first introduced Specialized only offered it in Europe. I read the limited market was due to two factors. 1) The price which only folks in Europe where willing to pay because they had more of a need for this type of transport. 2) The bike initial could go fast enough that most states in the USA considered it a motorized transport requiring license and registration. Specialized target market doesn't want to deal with that crap.

    From the pricing I'm guessing it's now available in the USA. $3800 is still pricey, but less than it once was.

    Why would you want to do that, and *not* be on a motorcycle?? If you're going to be legally stuck to streets, at lease a motorcycle/scooter would be able to keep up with the bulk of traffic. Offroad, It's just going to take a few idiots on "legally motlrcycle" bikes running into old ladies and kids (or worse running into a lawyer who's active on the local government board on his $4k cervelo) on the bike trails to turn an awesome trend towards smaller footprints into regulation nightmare. There's already been huge debate about that here in my area. If you ask me...28mph caps...I'd be happy with...even though I'd have a blast taking bigger bikes out. Just out of prudence, and an interest in keeping out of legal woes. Would hate to lose access to the bike trails around here (read: no stoplights), just because a bunch of yahoos are running over old ladies.

    I have been pretty happy with my 2007 tech 1,500 dollar (when new, I got it for 500 used) electric bike. It had an all aluminum frame, 8 speeds, V-brakes, 18 MPH top speed on motor, 12-35 mile range depending on how much you pedal and this was when it was ~5 years old. It also weighed under 50 pounds with NiMH batteries, the only downside to me was that it's a purely pedal assist with no throttle. My ideal electric would have a twist throttle and possibly pedal assist as well since it's actually pretty nice. Basically you can lightly pedal yet get to respectable speeds.

    (205 for the 205th time posting this pic :lol3)

    It still had some respectable juice left in it as of last season though they definitely have lost some of their charge....they're 8 years old though so I don't think I can complain too much. I'm debating rebuilding the battery pack though I'll have to do some more reading to figure it all out, the replacements probably have pretty old cells by now and are 500 bucks....I'm not going to sink that much into this old tech.

    I really want a full on electric motorcycle but a much more capable electric bike like those posted here would be interesting especially if the prices come down.

    If I were to buy one today, I'd probably go for one of the fully-suspended Haibikes. It looks like a lot of thought went into their designs. I like that the motor is at the crank-hub, rather than in the wheel like on many bikes.

    But I'll probably wait a year or two and see how the market changes. My motorcycle should be out of the shop in less than a week.

    When I was in the local BMW shop I noticed they're selling something eerily similar to a Haibike.

    It has all the main design elements. The Bosch hub/motor, in particular.

    Yeah, I have been researching this for a project this spring and I think the Bosch unit pedal assist/mid drive bikes are really nice insofar as range to $$$$. You are still looking at 3.5K + though for one of these bikes...and it goes up from there.

    Another option is the kits like the Bafang 500/750W units. I really think I'm going in this direction - mount one to an older hybrid bike I have and see how it goes. Cost is under 1K with a good WH Lion battery pack. I really like the idea of the pedal assist...the only thing lacking is the torque sensors you find on the higher end bikes like the Haibikes, et al.

    Perhaps mechanically but that's no commuter bike. You said commuter bike, where are fenders and racks. You probably saw they do make this though..

    About a year ago I really looked at e-bikes for my 20 mile commute. Most were rear hub designs--- but for what you are looking at I think you are smart to be thinking Bosch- crank hub designs. Partially for weight and for if you are riding it off road at all and have a puncture. Changing a tube on a rear hub looked like a huge pain in the ass.

    Fenders and racks are things you can put on any bike, so that's relatively unimportant to me. I'm just looking at the basic designs. I don't need standard modifications to be an OEM at-initial-purchase item.
