I know I"m a bit off topic here since you want to buy prebuilt and pedal, but here is a new scooter coming out I saw. From what I have read they are the best.
http://www.superscootersales.com/?pa...&product_id=60

I'm with Metallover, get one of these motors
http://www.thesuperkids.com/hi2hicumo.html
slap it on your bike with a 5k thumb throttle for 50 bucks (no sep controllers needed)
and 7S of the 5k 20C turnigys (dont do 8s it frys the motor, I know this)
as many as you need to get the distance.

I bought an old currie phat flyer scooter for 50 bucks that I upgraded with the turnigys, kept the stock 300w motor on 8S and it just flys. 22mph and I weight 160 pounds. Since the lipos are so small compared to the standard lead acid batteries you can fit just about as many as you want.

I think the wattages are deceiving for those motors as they are big as rocks, but only rated at 300 or 400watts.

I just got a phone call and got confirmation of the price on this Motorino mountain bike I linked. It's $1900 CDN.

Those are some nice bikes you guys have linked to. The only thing I dont understand are the prices. It think they are all trying to make a nice little profit. You could build a nice bike with plenty of motor and capacity for under 1k. I do understand the want to get one pre-built though as you really dont want to get stuck on your trip.

If these guys can really get 10k for an electric bike I am in the wrong business.

They are cool, but no where near 10k cool.

I agree, I was hoping for 4 to 5k. I responded to them in a nice way and let them know that I was going to look at other options because there are a lot of them out there.

I'm communicating with a woman called Julia from ebike-bmsbattery.com.cn. I told her I am a big guy at 6 feet and 225 pounds. I need something to commute to work (10 km) and to run errands and for fun on the weekends. I plan to purchase a sturdy and good quality full suspension mountain bike with disk brakes and 26’’ rims much like this one.

http://speedriverbicycle.com/product...-5-73320-1.htm

I would like a system that would bolt on a bike like the one I linked and give me good acceleration and a top speed of 40 km/h or more. The city where I live has a lot of hills and slopes, it is not flat ground so I need something with good torque to climb those hills.


So she replied by suggesting this kit.

I am now waiting on the pricing of this kit.

aqwut 03.12.2011 12:05 PM

500W is plenty to get over 50KM/h. I sell e-scooters on the side, on 48 volts the 500 watt motor will be good. I weigh 230Lbs and my GF weighs 105Lbs. And it gets us to 45Km/h 300Lbs +. On an e-bike with pedal asist, you'll be fine.

mistercrash 03.13.2011 10:07 PM

I just got the price of the BMS Battery 1000W system.
Not to bad at all, except for the shipping cost. But I guess that's to be expected with the size and weight of the package.

8 - 48V Thumb Twist Grip Throttle(Battery Meter and Switch)---$5.0

I went to SpeedRiver Bicycles here in my town and they sell the BionX systems that they can install on your choice of bicycle. The BionX system has a lot of features that make it very desirable over other systems I've seen searching on the web. The system is stronger than I expected according to what the guy I talked too said. He was very knowledgeable about the product and the company itself. He actually had a guided tour of their facilities. The system wouldn't have any problems hauling a big 225 pound guy like me around tackling steep hills. I like the regenerative feature of the system.

That thing looks cool. But it starts at $5500. A little too much for me. I'm moving forward with my plan to go ''gasless'' in the near future. We have two cars, a 2007 Toyota Rav4 and a 2004 Toyota Sienna. My work is 2 minutes away from home so we really don't need two cars. So the plan is to get rid of the wife's Rav4 first, it's not that bad on gas but it's suspension is hard and the seats are not comfortable. We traded it in for a fully loaded 2007 Mazda6 GT wagon. About the same gas mileage as the Rav4, maybe a tad more but the ride is much more enjoyable. This car is temporary anyway, we don't plan to keep it more than three years. Hopefully just two. Then we want to sell my Sienna and replace with an electric bike. We are interested in electric cars that are hitting the market and the Chevy Volt looks cool. But it's a brand new model so we thought, let's drive the new Mazda a couple years and let GM fix the bugs out of the Volt and in two years, start shopping for one to replace the Mazda.
So now I need to sell the minivan to get the E-Bike. I am still debating if I go with something that is ready to go like this or a system I can incorporate to a bike of my choice like this.

mistercrash 05.03.2011 11:13 PM

The minivan is sold. I spent all weekend cleaning it up and making it look as new as possible. So I'll soon be riding around on an E-Bike to go to work, laughing at all those people driving those SUVs paying $1.38 per liter. :yipi:

snellemin 05.04.2011 02:53 AM

Nice man. Ebiking is fun on my daily commute to work. I say that you would need a min of 500W of motor for your weight. HV is the way to go, so 48V and up.

My big SUV is purely a family vehicle now and the Camry for long distance commutes/errands.

There is always that cheap Ebay kit to start you off with your Ebike build. 14S lipo and you are good to go.

Great info
 
All of this is truly great info. The one thing I really like is having the informative dashboard. Having all of your technical info displayed in real time is some thing that we are all used to driving our cars and motorcycles, so having the same headsup info on an E-bike is a must. Most of these kits seem fairly simple to install and setup as long as you have a clue for what you are doing and what you are hoping to achieve. Purchasing an E-bike RTR really keeps things simple, but considering the price and how simple these systems are I would rather build my own. You can save money, you get to set it up the way you want, and you become intimately familiar with how it works and what it might take to keep it running well.

The biggest problem I see so far is finding a worthy battery setup that has enough power for speeds in the 30mph-40mph range, and run times that will reach 30-40 miles under full power, and still keep the cost reasonable.

Pricing a setup for one of the kits sold on ebay is tempting at less than $300, but when you add up what a good battery setup will cost you it can get quite pricey. The A123 3.3v prismatic cells run about $50 each. To build a 48v, 20amh battery pack your looking at about $1000 just for the battery. Of course this is the newest technology and keeps the size of the battery small. I am still thinking about it though.

By the way Snell I love the "T" shirt.

mistercrash 05.04.2011 12:35 PM

I gotta get some of those T-Shirts :rofl: I went to the E-Ride dealer in my town and tried a couple different models of electric scooters. I was curious to find out how they perform. I was set on an E-Bike but now I'm seriously considering a scooter instead. They have a max speed of 45 kph which is more than the RTR E-Bikes that cost almost the same. These scooters are just under $2200. They even have a cup holder :mdr:
Even if you got a cheap Chinese kit off ebay to build your own E-Bike, it would end up coming close to the price of that scooter if you factor in the battery you have to build, all the supplies needed and a good bike with disk brakes and full suspension. Plus the time you spend tinkering on the thing is valuable too. And you're on your own when it comes to do the maintenance and repairs and you don't get a warranty. To me this is also valuable.
This E-Ride dealer also sells electric motorcycles that have the equivalent power of a 100cc gas motorcycle and have a max speed of 70 kph. But you need a motorcycle license and insurance to ride them. Now if there was a way in the future to get my hands on the power system of an electric motorcycle and secretly put it in the scooter :yes: :mdr:
