Re: Basic geared hub setup BUT high voltage battery, help needed.

I guess you are right that most 48v controllers will come with 63v caps and will probably work. Some controllers have a High voltage cutoff though, I have 2 that will not work with a fully charged 14s battery, I have to discharge down to about 56.5v before they will work. Better do some research on ...

Re: what do i need ? a better controller ?

A "better" controller will probably not give you more speed, and might damage your battery. It is important to match the controller current draw to not exceed what your battery can deliver. Without knowing the specs on your battery, motor and controller it is hard to identify what is bottlenecking y...

Re: Basic geared hub setup BUT high voltage battery, help needed.

The bpm is a geared hubmotor. So is the Mac. As far as I know they are the most powerful geared hubs available.
In my opinion they are the most versatile motors out there. The bike will still be pedalable, but there is enough power on tap to make it fun to ride even with minimal pedal input.

Re: Basic geared hub setup BUT high voltage battery, help needed.

That battery will probably not work with the typical cheap "48v" controllers. As it is an unusual voltage you will have to buy a programmable controller. I have never used a q128, but i seem to remember reading some not so good reviews on it. If all you want to run is 20a, i would recommend the q100...

Re: 15/18F Silent Controller 36-150V BT-iOS-Android/GPS-$179

I was pleased to discover that the gps/gsm unit is a tiny little box that can be easily hidden. My plan is to shrinkwrap this ...

Just remember that you have no short circuit protection if you bypass the bms for discharge.

Re: Questions about Bafang motors

I assumed you were talking about the bpm motor since you mentioned 500w rating earlier. The swx is a 250w rated motor i believe but I have never used one so I dont know anything about them. I would be careful pushing 1000w through such a small motor though.

Re: Questions about Bafang motors

I would guess about 75 nm torque on 48v 20 amp controller. It will definitely smoke your dd hub off the line and should keep speed better on hills.

If you go to http://www.ebikes.ca/tools/simulator.html you can enter your data and check what performance you can expect.

In Europe the NEDC-standard is used, America uses the EPA-standard. 2) Shouldn't there also be a standard for the projected range at a certain age? (They shouldn't be quoting the range as new because it wi...

Re: Will 1500 watts be enough for motorized bicycle racing

I found a nice article about this.

The club in the article has races with several different classes with power apparently ranging from 2 hp to over 12 hp. Honestly it looks like great fun.

Re: Will 1500 watts be enough for motorized bicycle racing

I know nothing about ICE powered bicycles and even less about racing them. What kind of motors do they run? Do they have power or displacement restrictions?

If you are to compete they will probably give you some restriction on the power to not make it unfair.

I run my bpm2 at at 1500 watts with the stock nylon gears. From what I read the clutch will kick the bucket before the gears unless you get the motor very hot.

What are some good street tires for 19" moped rim?

I am looking for a good tire for a 19" moped rim. The rim is 1.6" wide. The bike will be for street only so I want a fairly smooth tire with decent rolling resistance and good puncture protection. If you have good experiences with a tire please let me know.

Re: Mxus3k 3t on 48v. Bad idea?

I know i could get by with a smaller motor. A 9c would probably be enough for 90% of the riding i want to do.
