Computer set up

[Robin Jeffrey]

Hi my name is robin
I recently bought a bike on eBay from a private seller who converted a new bike to a emb.
The bike is a carerra vengeance with a 1500w rear motor with the controller combined in the motor, there is 8 magnets on the pedal crank, it has a twist throttle, it has a 48 volt - 13ah battery and is controlled with a sw900 screen.

The bike was set up ready to ride when I bought it, but I am wondering about one of the setting options ( speed measuring magnet) range from 1 - 100. At the moment it is set at 46,? Why would that be, why so many options, I imagine a lot of the options are going to be wrong. Can you advise what it should be and why, just so I have a better understanding of it.
Also I never seen more that 920 watts assistance on the screen, is that due to battery size.
If I was going to upgrade to a more powerful battery would I have to change any settings, for example 48v 21ah.
Or could I fill a 52 volt battery without damage to the motor. Any info you could give me on the above would be much appreciated. Thank you. Robin Jeffrey

OK, 46 is the default setting for a direct drive motor. There's nothing to be gained by changing it. The ONLY thing that setting does is to properly calibrate the speedometer. Go ahead and mess with it if you like....

RE: the 920 watts, controllers that are built into motors like this one are not real well known for their performance capabilities. Nor is any other direct drive with built in controller. This is a very inexpensive drive with limited performance available. It's designed to provide transportation in fairly level terrain. That's about it....

A 48v 21ah battery would have no more power than the battery you have. However, it would increase the distance the bike could be ridden on a charge (all else being equal).

The 52v battery, if your controller could be set up for it, will be SLIGHTLY faster (all else being equal). I would add that trying to justify spending that kind of money for an extra couple miles an hour may prove difficult.

Ok thanks for the reply.
I get the impression you don't regard this kit very highly, that's fine I always like an honest accurate answer. I paid £1350 for the emb, is their a better emb for same sort of ££. Or a better kit . Do any of the emb's or kits produce the power that is claimed, I understand that a 1500w motor is only going to produce that at Peake power for a short time, where as my set up peaks at 920 watts and that's just on initial start up then after 700watts cycling up hill, which is really all I Need, but a long way off 1500w.
Is there a more accurate description or term to describe the motors output of what you can expect to see when you are using it, hope that last question makes sense.
Is £1350 enough to buy a better setup than what I have or is more needed. What would you buy. Say what you think I won't be offended, just more knowlageable cheers

Actually, I think £1350 gives you a pretty good budget, if I'm converting that to US dollars properly (1659.). Have you checked out something like the RAD Rover? Not sure what a bike that best suits your purposes would look like.

This bike? Are you somehow unhappy with it, or think it is not performing as it should?

Ok I will check out the rad rover and anything similar to it, I might help my son buy a better bike than mine, and if he doesn't like it, there could be a chance it will come back to me. Thanks again.

Hi, I'm happy enough with assistance it provides on the up hills which can be 700watts or there abouts, it's the fact that it never displays anywhere near the claimed 1500w . Just think how much happier I would be if I had 1500w pushing me up the hills. If your car only produced half the power it was supposed to it would be up for sale or heading to the garage.
I imagine you have an emb if you are reading this what model do you have and how do you rate it. Thanks robin
