Meanwhile, the 0-5V variable regen brake current could be set maximum, equal to phase current.
refer to below setting.

Hi there

I'm interested in a 2000w V3 hub motor for an electric bike in a 24in rim.
It will be for a lithium battery on an electric enduro frame ( 154mm Dropout width)
the bike and rider will be a total of approx 140kg

how much would it cost including building into the rim and postage for australia?
please let me know if further information is required.

Thanks!

Hi, I'm thinking of converting www.rieju.es/m/16/450/rs3-nkd-50 one of these from a non runner to electric in UK - as a motorcycle (not limited), using a hub motor for simplicity.

Likely use - city commutes in traffic
Range - about 25 miles
Acceleration - desired as good as a 400cc Suzuke burgman scooter
Top speed - able to cope with occasional trips on the ring road so able to get to 70mph for short periods e.g. up to 5 miles

I would welcome a sanity check as to whether this is achievable at some reasonable level of cost?

Please may I ask you to keep suggestions to hub motors

My starting point is www.qs-motor.com/product/8000w-spoke-hu ... motorcycle

Your suggestions very welcome

I know UK is pretty straight forward to get a one-off build registered as a 45 km/h moped. Changing that to an A1 or even A without any limitations I would imagine that would be a much tougher task, can't remember seing anyone in the UK done anything different then a moped 45km/h legal build here on the forum. There are a few threads about what it takes to get a build road legal here on the forum. Search function will go a long way. You might find that is cheaper to get bike registered as a A1 motorcycle. Those are limited to maximum output power of 11 kw continuous. Note that it is 11 kw continuous output power. A1 bikes are not speed limited. You can ride highways and toll roads no problems, and you will be able to keep up with traffic. That means you can have 30 or 40 kw peak output and still get it registered as a A1, which in turn should yield cheaper insurance etc over a fullblown motorcycle class A.

I would anyway start with a phone call to your local DMV and check with your local authorities what it will take to get the build road legal. As a one off you don't need a full road and crash test, so it should be manageable. In UK afaik there ain't even no requirements to have a third party inspection done by sertification companies like the TÜV. The cost for this process I have no clue, but your official DMV should be able to help you with that.

As for the build itself that motor will work well for street riding, even if it is heavy. Be sure to pair it with a controller that can deliver loads of amps. 600 amps at least. More is merrier, for rapid acceleration. For off road usage that motor might make the build a little tail heavy, but dirt road and fire roads should be ok without going full throttle. Also take it easy in corners in the beginning to you learn the limits of tractions, such a heavy motor in the rear wheel can give you a few surprises in the beginning.

Thanks macribs you raised some good points

I have a full motorbike licence so thought unrestricted - will look at A1 as well.

Road use only

Hadn't thought about unsprung weight on rear - presumably that's why some use mid drive

Two of these:

And you will need two of these:
http://www.cnqsmotor.com/en/article_rea ... r/799.html

Then a battery pack that can provide the needed current and has enough Ah to last the distance you need. Ask QS for a matched motor/controller kit. It'll probably cost north of $4000,- incl. shipping and excl. taxes and the battery pack.

Hello,

I got a bill (first warning) from TNT for shipping two motors and a rim from QS factory to Germany (127,26€) from the 10th of September 2017 (today is 14. Novermber 2018). I payed it but I wonder if I really had to as I remember to have payed for shipping together with the motor. What is this? Do I really have to pay for shipping? I ordered two motors and a rim back then.. If you want I can upload the pictures of the whole bill I made back then.

Please answer QS motors! Im confused about this!

The packages were send at the 25th September 2017
Inv. no QSMW17EL0731001

Are you sure that bill was for shipping, and not VAT or handling fees for import paperwork? When I order from China I usually get a bill at a later day then arrival of the actual package. First package is received and signed for, then later the bill comes. In Norway we have 25% VAT on top of the total amount of sale + shipping. And the shipping company usually deals with the VAT and paperwork, I think they actually pay the VAT upfront, then collect from customer later, and they also slap on a handling fee on top of the VAT.

I know you don't pay VAT for purchases within EU in Germany, but from China my guess is 17% vat on top of the purchase price.

Hi there,

I’m thinking of using one of the QS273 motors in a motorcycle conversion and trying to see if it will fit in my swingarm. The standard dropout/swingarm size for these motors is 200mm. My swingarm is ~210mm but need to put the brake caliper mounting bracket in there as well. Can anyone tell me if the circled part of the axle below is a spacer to keep the wheel in the middle of the swingarm or something else and is it removable? I was thinking of replacing it with the brake caliper mounting bracket.

The drawing comes from http://www.cnqsmotor.com/en/article_rea ... r/245.html

Depending on what it is and whether or not it’s removable, I might end up getting a custom axle when I order the motor.

Thanks!
