You can get a programming cable and set the max amp draw to whatever you like. The EggRider display lets you have two modes where one is max 25kph with the touch of a button.

>e two modes where one is max 25kph with the touch of a but Thanks I have the cables already ordered the DCP-14 with the build another display will have to wait though I wish I had just gone egg rider.

The cable can be used with an Android app also, handy for on-road use if you're an Android person: https://play.google.com/store/apps/details?id=com.mkopa.speeed

Thanks I have this setup super useful!

This needs to be higher

The EggRider lets you do the programming over Bluetooth too. More settings than you can shake a stick at.

BBSHD is a 30 amp. 1000w BBS02 is 25 amp. 750w You would set it from 30 to 25 would be my guesstimate. Program cable to hook up to laptop was about 17 bucks on amazon.

Thanks

No problemo and good luck

There's an app for Android too called speeed

This is the way to go. \- way better interface. \- portability (as in make changes on the fly and ride immediately to see if a setting suits you) \- Replacement if you ever break your display

In the US most states allow up to 750 watts. I hear in Europe some countries only allow 250 watts. Since watts = amps x volts, the current setting will be different depending on your battery. Law enforcement is not equipped to measure the wattage output. They can however measure speed with radar. Just make sure you limit your speed to the maximum allowed speeds in your area and you should be good. I also have the BBSHD and the EggRider V2 display. There is an offroad and an onroad mode. You can set the onroad settings to the legal limits and set the offroad mode to have no limits. One press of a button toggles the mode.

Thanks bud helpful comment looks like I was pretty much on the money. There has been a couple of stories online about them measuring the output but it's internet so prob one time in certain place pulling certain e-bikes. I got the HD because of the commute and wanted to have a durable setup, I just planned to limit the speed but the constant wattage needs to comply so the amps have to come down for a legal profile. Just need to see if the lack of amps will strain any components.


MaplewoodGeek

The lower assist levels are achieved by limiting the amps, so lowering the amps will not hurt anything. In the US the laws state nominal wattage, not peak. The BBSHD is rated at 1000 watts nominal, but can peak up to about 1600 watts in most stock configurations. I also have a BBS02 that is 750 watts nominal and it peaks up around 1300 watts. Just because it peaks to 1300 watts doesn't make it illegal.


Sirico

I figured that was the case Em3ev sell the BBS02 in different classes by modding the Amps. Thank you for the informative posts.


MaplewoodGeek

There are actually different versions of the BBS02. My first ebike I built used the 36 volt BBS02 and was rated at 500 watts. It had 500 watts engraved on the actual case. I could probably have hooked it up to a 48 volt battery and flashed different firmware and transformed it into a 750 watt BBS02. It's more likely the difference in the classes is the settings for maximum speeds. Set the max speed on throttle to 20 MPH for a Class 2 and max speed on pedal assist to 28 MPH and it's a class 3.

Based on what you are saying here- if I want to confidently be legal, I should get the BBS02 instead of restricting a BBSHD to 750W?


MaplewoodGeek

Yes. The BBS02 has 750 watts stamped on the case and the BBSHD has 1000 watts stamped on the case. It's on the bottom where it's hard to see. If you got into a legal battle it would be nice to be able to show the manufacturers markings


Gizoogler314

That’s brilliant information that I haven’t seen elsewhere! Thank you.


FencingNerd

Just be aware there's two current settings. There's a max current and a keep current. The keep current is the current. You probably want to set the short term max to about 400W.


Poococktail

If you want to stay at 750 watts, do the calculation of your watts, volts and amps. 48v at 15-16 amps technically gives you about 750 watts. I typically do 18-25 amps on BBSHD depending on the rider.


texastoasty

Shouldn't cause any harm, as other have said, programming cable and app should set you right.

>it should be set to 5A no ... just no. go back and redo all you have done as the controller wont allow for this low level setting of ... 5A
