Magic Pie & Smart Pie Discussions / I can not set PAS to assist pedalling. Pedals is more like a throttle
« Last post by Jai134 on June 14, 2026, 07:33:17 AM »
I use Bluetooth and an android mobile phone and I can not get my PAS settings to work well. If I change ratio to 100 it kicks in on level 2 but not 1. If I lover it to 60 it works at level 3 but not 2 and 1. When it kicks in it accelerates like crazy up to approximately 20 km/h and I need to pedal very slow to keep a constant speed. I just control the speed without adding any pressure to the pedals. There is no correlation between pedaling and motor speed except for starting the motor.
Ratio is set to 100
Acceleration to 30
Current to 15
I havent changed anything else except for throttle which is "close". That is still working though.

Magic Pie & Smart Pie Discussions / Re: Magic Pie 5 Brake Levers...

Hi Harpo,

Actually, just the opposite, as the contacts or circuit must be OPEN for the controller to operate.

I.E. The Magic Pie brakes are Normally Open (N.O.) and close when braking is applied.

But I have to say I always recommend using brake switches for safety reasons. For me they have proved more than helpful, more than once... just sayin.



Regards,
T.C.

Magic Pie & Smart Pie Discussions / Magic Pie 5 Brake Levers...
« Last post by Harpo on June 11, 2026, 12:58:48 AM »
I'm installing a Magic Pie 5 w/internal controller.  If I do not use the supplied brake levers, must I short those connections at the harness for the motor to operate?

Thanks in advance,
Harpo

My main reasons for selecting 26" vs 20" rear are better top end, a little better ride, and ease of usable ratios with stock chainwheel.  It's also the only Magic Pie 5 available with internal controller, another feature I wanted for clean installation. 

The Rover chassis will accept a 26" rear with no modifications.  I've run across quite a few on the internet who have done this, and Utah Trikes even offered a model built this way, the Rover X-5 (https://www.youtube.com/watch?v=RdBTSRkgeIE)  I also spoke directly with TerraTrike, they confirmed the change is often done, no issues reported.

With the stock 20" rear the Rover sits 3" low at the rear, so the 26" merely brings it level.  Overall caster change is minus ~4.3°, maybe a little bit twitchier but the adjustable tension steering should make it manageable.  The Golden Motor rim is a surprisingly good looking alloy 26x1.5x36H, so tire width remains 1.75.

Magic Pie & Smart Pie Discussions / Is it possible to set up PAS without bluetooth
« Last post by Jai134 on June 07, 2026, 12:50:21 PM »
I'm not sure but I think that I set PAS to "close" in the android app because I didn't plan to use it. I changed my mind and now I have a PAS sensor mounted on the bike but cannot find the bluetooth dongle.
Is there a way to change PAS setting to enabled from the LCD? I have "BAC-601" LCD display.

I think everything is correct in my setup, only thing I can think of is that the magnets are too close to the sensor. They're almost touching.

Hi Harpo andto the forum.

I'm curious as to why you would use a 26" MP5 instead of a 20" MP5.
I suspect that the original frame is capable of accepting the larger diameter rear wheel, but you will probably find that the width of tyre that you'll be able to use will be reduced as it will now be located in a narrower part of the chain stays.

The 20" MP5 is a solid cast wheel that would be much better at resisting the high lateral forces that it would be exposed to when cornering at speed on a non-tilting trike.
Also, being the same diameter as the original wheel it wouldn't decrease the castor angle on the steering by ~3° or raise the Centre of Gravity.

New member here, adding a Magic Pie 5 26" to a TerraTrike Rover along with rear derailleur, replacing 20" with SA internal 8sp.  I've got almost all the parts now, will be starting soon!

Now I have tested the updated version in the boat.
It works well - but...
In the F1 position the motor is not running. I have measured the output voltage / propeller RPM as follows:
F4: 3,639 / 576
F3: 3,210 / 379
F2: 2,881 / 177 
F1: 2,545 / 0 ??
N:  2,214 / 0
R1: 1,781 / 153
R2: 1,345 / 270
R3: 0,908 / 389
Note! The propeller RPM is 1/3 of the motor RPM.

Now I have tested it and it works. When switched on it beeps, as it is in neutral and the brake signal is active. Rotating clockwise, speed is inreased forward, and counter clockwise reverse.
However, sometimes the beeping does not stop and the motor does not run, when I turn the throttle. Maybe the voltage on the throttle input is outside the limits. I will add the TP3 potentiometer to be able to fine tune the neutral position, but connect it to the N connector instead of the output.

Magic Pie & Smart Pie Discussions / Forks for 1000 watt Magic Pie 5? ..
« Last post by diverdon on May 29, 2026, 03:18:33 PM »
   Thinking about upgrading the forks on my Electra Townie 7D ... The motor has been on there for years .. 2 torque arms .. the nuts have only backed off 3 times in all the years .. I'm pretty easy on it .. But .. That lower fork leg sure looks thin .. A fork called the Surly Troll looks like a good fit ... Any suggestions ?
