Will this fit this? / Whats the fastest you ever been on a bike?

http://www.ebay.com/itm/48V-1000W-Fr...ht_2979wt_1163

http://www.schwinnbikes.com/bikes/ur...d-14284#/specs

Its a little experiment i want to do. Its gonna cost me $800 and i want to make sure everything fits before i commit.


So does this Motor / Rim fit that bike? And if not can you point me to a bike that it will fit (Preferably with fenders)


**Just for fun

Whats the Fastest you ever been on a bike.

Me i believe it was about 28 MPH on a flat road chasing a car. Long story short.. the car got away...

About 60mph, downhill with a fierce tailwind, according to the not-too-happy motorcop who pulled me over.

I'd love to get pulled over by a cop....maybe get a citation/warning to hang on the wall of my shop. That would rock.

I can generate 30mph on the flats, no wind.

Come to NYC. You'll get pulled over every other week.

So does any one know the answer to the question?

You really don't want long reach caliper brakes if you intend to go really fast. Certainly not cheap single pivot long reach calipers.

A the electric kit comes with a 26 inch front wheel and motor. The bike has 700c wheels. I don't think it will work.

On a short straight downhill on a tandem...56 mph

Single bike..........46

flat straight....34

On a mtn road with switchbacks 38.8. I hit 40 before I had the Garmin couple years back.

This is what 38 looks like on the mtn road and swithcbacks from my pov.

I'd look for a decent rigid MTB. Wonder what effect the weight of the motor will have on the front fork & handling?

I think I've been to 120 on one or two occasions. I'd never do it except on a straight, perfectly dry road with minimal traffic, in a full face helmet, a leather jacket, and heavy gloves.

Now, if you want to know the fastest I've been on a bicycle, I'm pretty sure that I went above 40 mph a few times, and my GPS shows me hitting 46 mph once, but that one might be a GPS glitch. I'm generally too chicken to pedal downhill, on account of having no real body protection. The fastest I went on anything resembling a flat road (not that we have many of those here) was 35 mph with a fierce tailwind.

With regard to the electric motor, I recommend that you check the laws in your state. Here in California any bicycle with an electric motor is legally restricted to 20 mph. A 1000W motor would be a huge overkill. It would be capable of pulling you at 20 mph up a 10% grade.

I don't think there's any way to use that with disc brakes.
I would look for an older fully rigid steel mountain bike or a good quality cruiser. And make sure you use a strong rear wheel and that the spokes on the front wheel are properly tensioned.

Actually electric bikes are in a legal grey zone in NYC
The key is if i go 20MPH or faster really. But im kinda looking at it much like sports car owners do. I wont go that fast.. But i would like to have the ability too MUHAHAH... Any ways i need to commute about 12-16 a day miles so i wont go that fast. Or else i might not make it back haha



Last on the other site i was referred to it says that you can use disc brakes with a hub. A lot of time you just need to get the spacer. I dont know if i need it but im gonna get it any ways just incase and ill see when i put the bike together...


Also how much is the shipping on that bike on amazon?

Another question... How cast can a bike physically go before it starts to fall apart?

I checked the vpower.hk website and didn't see any reference to disc brake compatibility or a disc brake adapter.
http://www.vpower.hk/product.php?id=40
If you plan to use it with disc brakes you should probably email them and see what you will need and what issues there may be.


Also, I'll be very surprised if vehicle classification in NYC is based on current speed traveled and not on the speed the motor is able to propel the vehicle. You can use a cycle analyst to limit the speed.

Local Cycling club had a Time Trial a couple of weeks ago. The one spot on the road that had a 40mph limit on it and the Police set up a speed trap. 6 competitors stopped and Charged with "Riding in an aggressive manner". It was noted that NO cars were stopped and locals have never seen a speed trap on this section of road before.

Bicycles are prone to so-called "speed wobble" above 40 mph, which is not exactly starting to fall apart but scary enough to make you slow down. The point of onset of speed wobble is highly variable depending on the bicycle and conditions.

The second biggest risk, with rim brakes, is tire overheating and exploding during braking. This is part of the reason why disk brakes are often used on tandems (two riders -> twice the energy to dissipate at any given speed). But if it can happen with a tandem, it can also happen with a single-person bike, just at a higher speed. I can't put a number on it but I imagine that braking from 50 mph to a full stop should get you pretty close.
