bbso1 250w max speed change?

[flik9999]

Hello how do I change the max speed of my bbso1 juat installed and max speed is 30kph i want it a bit faster

I haven't played with my screen settings for a while either long press + & - for 10secs to get in the settings or hold off & +, you can adjust up to 40kmh.

Um that didnt work pressing up and down put it into mode 'p' and it just accelerated. off and up did nothing.

 

[flik9999]

Can I also unlock the power by taking the magnet off? This would mean I wouldnt know how fast I was going tho.

 

[Nealh]

Had a quick play with my bbs (original 01 version), switch on then long press + & - simultaneously when screen changes use on/off button to toggle through the screen. Can set to 50km/h max.

If it doesn't sense the magnet you get an error 21 and drive will not work.

+ and - is up
amd down right? When I hold them down it goes into assist mode p and the back wheel starts running thats all that happens.

Oh just realised my buttons are different the control panel has 4 buttons nut up and down.

Figured it out. It appears my kit is an E Rad bafang mid drive. Ebay seller lied but I figured it out.

I went in and set max speed to 50 kph and an getting about 24/25 mph. I guess thats kinda the max for 36v systems?

Depends on your size/weight etc, 24/25 mph sounds a bit optimistic for a 250W unit, 20 to 22 on the flat with no wind I would have guessed.

You should be able to get 45 km/h (28 mph) from a 36v BBS01, I can from the GSM. The secret is using the right gears and spinning at 80 rpm - 700C x 38 tyre at 80 rpm gives 44 km/h using 46:11 ratio.

I have 700C 2" Big Ben tyres 42:11 and spin at about 90 rpm http://www.bikecalc.com/speed_at_cadence

Im running 46x11 top gear with 700x25 racing tyres.

However bike is not that aerodynamic and has platform pedals. Would other bike stuff help me get up to 28 such as spd pedals and aerobars.

Also what is the legality pf the bbso1. It is 250w but can be changed through the controller.

I know there is a list of phrases you can say to cops if pulled over.

Your theoretical top speed will be 42.36 km/h http://www.bikecalc.com/speed_at_cadence

At over 25 km/h you are going to need to fight air resistance and that is where the motor comes in... I am a reasonably fit 60+ yr old man weighing about 80 kg on a bike weighing 23+ kg. I have ergotec flat pedals and a moon bar so I am sitting up reasonably straight.

If I de-restrict and use assistance level 5 I have my Watts, about 150 - 160 + motor Watts of up to 500 depending on the state of the battery say 650W. If you punch those numbers into any online bike calculator you will see that 45 km/h is possible on a 250 W pedelec if you have the right gearing.

Watch out for cars! They see a bike and guess you are doing 20 km/h and not the double...

C965 display press + & - for a couple seconds and release .Repeat.Now 4 zeros will display.put the code 0512 in pressing ok after each digit .Select your speed .then after pressing ok wait a few seconds and it will revert to the regular display.Or cycle through the remaining settings by pressing ok.

Hmm ok so, another thing is it only has 3 levels of assist. Is there a way to unlock the other assist levels?

 

[Nealh]

Will need reprogramming to get 5 or 9 assists.
A lot of user prefer 5 levels so reprogramme from 9 to 5.
You will need a prog cable/lead and download free software plenty on hoe if yo do a search om here for BBS reprogramming.

 

[malkie0831]

On my DPC14 lcd display the number of levels is set on the ‘Advanced’ menu item, which you need the password to enter. The password on this display is 1919.

The USB programming cable does not give access to the number of levels offered by the display.

 

[anotherkiwi]

5 levels is plenty. 3 levels would be enough if the controller was correctly programmed for them.
