Is it possible to remove the axle to install the HUB8EW into brackets with through holes that can’t be spread? Or is it drop in only?
Thanks,
Steve
No. It is not ok to do that
As you know I bought this wheel from you – the HUB 8EW. The supplied 2 inch tyre was unsatisfactory due to poor traction and bump absorption.
With considerable difficulty and some modification to the hub I managed to fit a 2.5 inch tyre. This was better but the controller or the twist grip throttle were most unsatisfactory, doing nothing until half throttle and then coming in with a violent jerk. This was most alarming when using reverse.
I regard the thumb throttle, which UU could not supply as much better. On a tricycle it is probably not necessary to have reverse, it’s better to have a freewheel so it can be wheeled around without the motor drag fighting you.
UU motor was unable to supply a wider wheel to the suit desired 3.5 inch tyre, this could not be fitted to the narrow rim. UU was unable to suggest a suitable solution.
I have rejected the UU HUB 8 EW.for a modified e bike bicycle hub fitted with a 3.50 X 6 inch tyre. Most satisfactory, but bigger than what I want for my lightweight folding “TravelTrike” design. Ideally I would fit a 3.50 X 4 inch tyre, no suitable wheel for this has yet been found.
I am looking for a hub motor wheel for the front of my prototype lightweight disability tricycle. Can you supply it with built in controller, thumb throttle and 36 volt lithium ion 10 amp hour battery in a bicycle drink bottle style container with all appropriate fittings.
The battery needs to be labelled to indicate the amount of lithium in it to satisfy airline safety requirements.
Please provide a price delivered to Australia.
Thank you ,
John Evans
Hello John, our motor is not with built in controller. What is your tricycle wheel size?
You ask the outside diameter of my wheel, I would like it to be no more than 9 inches, but would be OK up to 10 inches.
I bought the UU HUB 8 EW, but could not fit a fat enough tyre.
Do you have anything that would be suitable?
Hi tony, do you also custom a 3 phase motor for a 8″ pneumatic tire motor? Can i use a normal rc plane esc rated 100a for these kind of motor? How much is the shipping cost to Singapore for 1 piece only?
Thanks,
Zach
Hi Zach,
We can customize this motor, please send us email about your request.
Thanks!
Can you give me the weight of the 8″ wheel, we would like a 5 to 10 KM/H geared motor if possible.
Thank you
The motor weight is about 3kg, the max speed to 10km/h is no problem.
I want to use it in my e-scooter. What is its load carrying capacity. How much will it cost to me in india?
Hello Singh,the max load is 150kg, and the shipping cost to india is USD150.
Hi all. I am a newby here on the forum and am highly interested
in finding innovative disability aids that helps to
make disabled life more bearable.
Have some of you checked out this great little travelling wheelchair that folds and unfolds in 5 seconds and is featherlight enough to take onto train and if so ,
what do you reckon about it ?
Hi Danny, we do have a cooperator who makes quick folding electric wheelchairs. They are easy to take onto trian or plane.
We need to e-bike kit, but the engine must be subject in one arm. I watched without a kit for e-.bike have this engine. However, I see that produce these types of engines. Could you put together a kit for e-bike that includes a motor for holding one arm?
We need it rather urgently.
We welcome your comments
thank you very much
regards
For this motor, the max speed is 8km/h to 20km/h customizable.
Hello,
I’m looking for an hub motor with tyre for my electric scooter. Do you have mechanical drawing of Hb8ev? 36V is fine.
Which is the max speed?
Can ou issue an offer for 100 and 1000 motors.
Are you able to ship in Italy?
Best Regards,
Alessandro Bergamini
