Magic Pie III Updates

[Ingwar]

Jeff,
Thanks for your comments. Actually the aim of upgrading is getting an ability for short bursts of speed up to 45km/h and getting a range of 70km.
All the upgrades of bicycle(velo-) parts have been made to get a smooth, comfy and stable ride and maybe to improve the looks – black-white scheme with some red accents (that’s why some new parts are white and red). The bike is used for short in-town rides and for rather long out-of-town rides on different roads not necessarilly with good surface.

As far as I can see (on your avatar photo) – you’ve used recumbent as base for your e-ride so you’ll be able to appreciate the true value of changes that have been made (many parts were bought from recumbent’s suppliers)
The list of improvements:
Front wheel – Samagaga HC 100F-DB (light, stiff, with excellent rolling – Samagaga uses double-seal bearings)
Fork – Saso Carbon AC Suspension Fork (light, stiff, with adjustable hydraulic damping)
Rear shock – Rock Shox Bar2.1 (air spring with rebound adjustment)
Tires – Schwalbe BigApple 20*2,35 and Scwalbe tubes (Kevlar band protection, excellent rolling, additional comfort)
Handlebar grips - Ergon GP1 Biokork (excellent ergonomics and control)
Pedals – Truvativ Hussefelt (white)
Saddle – Velo Plush VL31 HD Men’s Saddle w/D2 Base (white) – it’s quite comfortable and good for long rides
Shimano GripShift 6spd.
Rear derailleur, cassette and derailleur hanger were changed cause had been damaged during transportation.

I like the design, but the quality could better.
Mine broke after one ride

Failing almost immediately is normal for anything electronic that fails. If you read the posts in this forum on failures, almost everyone one was "it failed on the first ride" or "it ran fine for a few days then failed". Sure there are exceptions, but that what they are, exceptions. Very few electronic items fail after being in operation after any period of time but it does happen. That's why is makes no sense to buy an extended warranty on any electronic product. If it doesn't fail during the regular warranty its very unlikely it would fail during the extended warranty period. Extended warranties are usually pure profit for the seller.

Yes I agree I have no luck

[MAGICPIE3FOCUSPOWER]

Okay after 300 km running time.
There is a knocking noise coiming out the motor, I suspect it is the big bearing problem

[MAGICPIE3FOCUSPOWER]

Okay I have replaced the bearing.

Running time is now more then 2500 km, but due the salt on roads.
The big axle is corroded and  when attempting top open the motor.
A lot of forces was needed, as resust the motor stator cracked.

So this is the end just throw it it the trash and bought HS3540 motor again.
Ofcourse I need to mod this motor, otherwise it will died in a short time (cable shaving issue).

I'm very sorry to hear your motor is damaged, but how and where was the force being applied to cause damage to the stator?

Any chance of posting some pictures of the damage so we can see exactly what has occurred.

Also, a bit more information about what you did could help to prevent others from causing similar damage.

I will make some pictures.

Well I have performed same steps when opening the motor before.
Just removed all screws, apply some at freewheel side axle.

But it didn't work at this time, so apply some force at disc side axle.
The disc side cover will now lift a few millimeters.

Now you can apply force at freewheel side axle to remove to big bearing cover.

This all what I did.

The big bearing is just to tight (corroded to axle) to remove.
So I think is the troublemaker.

I don't want to spend more money to make it more reliable.
This motor is not easy to mod.

I am riding 70 km a day, so a reliable and easy maintenance motor is welcome
But I had fun with this guy, too much power for some scooters when challenging me hahaha.

[MAGICPIE3FOCUSPOWER]

Here are the pictures.
As you can see the motor is fully modded
As I know the issues of this motor before, I wouldn't spend money to make this motor better

Hi,
I am having a similar problem, 2 months ago when I received the Magic Pie 3 48v.
It was working perfectly, then 2 weeks ago sometimes it didn't start on its own, I had to pedal for a few meters then the engine would start.

Yesterday he engine didn't start again, I pedalled for 200m and still nothing happened I only hear a small noise from the engine meaning it is alive but it doesn't want to turn. I only hear the noise if I pedal but it doesn't bring power. I tried in freeweel mode and even by turning the wheel by hand it is to weak to start. (battery fully charged, throttle showing green light, and same problem if I unplug the brakes and cruise control button)

Can anyone help me?
Thanks in advance

I think you have set a record for the most problems with a MP3. By far the vast majority of people have no issues. When its multiple issues I would think it has something to do with the end user. I have also cracked a stator one time. At first I blamed the motor. But after some time I began to realize it was how I took the motor apart. It had nothing to do with pounding the axle to remove it. It was the prying against the stator that did it. Even it the axle is corroded there is no force against the stator if its taken apart properly.

I do like the picture of the stator though. The coating on the wires is very nice!

Hi Mat,

You may want to start a new thread with your issue so it will be more noticeable. Then others in the future can reference it easier as well.

O  well I am just a high requirements end user.
Everything has to be almost perfect for me hahaha

Yes the big bearing axle is real corroded, no way to remove the cover.
It's protected from salt, snow, water etc....

But I had fun with the motor.....

[MAGICPIE3FOCUSPOWER]

Mat check the motor sensors...
