Just Bought XTreme Trail Maker - PAS issue

[Paul Heckmann]

Just bought an XTreme Trail Maker. Got it out of the box, put it together. Couple of short rides to tweak brakes, bars and seat...

My question - the PAS seems to go on and off. Its fully charged, the key is ON. I ride for a 100 feet or so and the PAS shuts off. Then it may or may not come back on. I can cut the key back OFF and ON and the on/off PAS cycle starts again.

My bad knees need this assist occasionally so I spent the extra bucks on a PAS bike. What am I doing wrong?

Move the magnet disc closer to the sensor. It's behind the chainwheel.

As d8veh has said, ensure the gap is very close like 1mm.

Thanks. I'll give that a shot today

Please let us know the results, as we've been kind enough to help you.

As far as I can tell, the magnet must be inside the sealed rear wheel hub. The wires go to the post of the axle, then disappear into the middle. Forgive me if I am missing something obvious. I'm a total ebike novice here

Can't see too well from the photo, but it looks like the pas disc is mounted on the inside of your chainring. It's a black disc about 60mm in diameter, with 8-12 little magnets set in it. On the frame, somewhere down there, there will be a sensor. The magnets should pass within about 1mm of that sensor.

On my bikes the sensors are on opposite sides. Look for something like these.

Thanks, found it

Thanks.

Now that I know what I'm looking at, as you can see from the pics, it appears to bent toward the magnets. The brass ring is exactly 1mm from the magnet but the sensor appears to be bent forward. Should I straighten that out?

The second picture is as directly over the crankshaft as I could get. You can see the tilt on the sensor

It should be an even 1mm gap. Just push it right.

Will do. I'll let you know!

Unfortunately no change - tried various widths with similar results. I have messages into the dealer and to Xtreme. I'll pass the results on when I get them.

Greetings. Turns out I had a bad battery. I explained everything you guys told me to do. Mfg told me to try a couple of things, then they said that they thought it was the battery, Mfg would not exchange by sending me battery. Had to send it to them up front in Washington. And I also had to pay for shipping. How they hell does a manufacturer operate like that? They also forgot to tell me that they had no keys for the batteries they sell, and I had to send that to them. Once again - how the hell does a manufacturer operate like that? And I had to pay for shipping - again. Then, they said - 'yes, it is the battery. we will replace'. Great. Then 'But we have no batteries. you'll have to wait another month.'
Just got it back Three months after this started. Not happy with Allco Manufacturing.
On the good side. I love the way the bike rides. Put quite a few miles on it already.

So, I ride the heck out of this bike. Put about 15 miles at a time in it, 4-5 days a week. Not too bad for an old fat guy!

But, I seem to have to use the throttle. I cant really feel the PAS, maybe just a bit in 3rd. Got on a new GIANT down at Bike World and felt how PAS should work. Mine is nothing like that. Any suggestions?

 

[Deleted member 4366]

Is the PAS working or not? What you said is too vague. Put the bike in its lowest gear, lift the motor-wheel off the ground and turn the pedals. Does the motor overtake the pedals?

 

[Paul Heckmann]

thanks for the reply. Tried what you said. No PAS with me turning the pedals until I reached over and hit the throttle.

Then Houston we have a problem

Sorry ,couldn't resist.
