Biktrix Swift step thru, bought Feb 2020 made some noise. Then exposed to sawdust. Subsequently throttle clogged by debris, hub motor continuous loud grinding since.

Hub sent to Bixtrix 6 wks ago *still no update*

Heard anything about Sawdust hub motor damage, or damage from light rain for a day which is person’s defence (full time handy man) am suing for operating power saw table to which bike was locked.

Following Sawdust exposure, hub Motor screeched clunked then went dead. Throttle clogged w/ debris cleaned w/ air compressor. Motor continuous grinding since, sent to Biktrix 6 wks ago, no update yet.
Bike swift 2020
Anyone have info sawdust damage to electric motors of any kind, or mechanism leading to clogged throttle?
NB am suing person who operated power saw table next to bike

[Duplicate thread with more details merged below...]

Anyone know anything about sawdust damage to hub motor, or any electric motor for that matter?
Swift hub Ebike 2020 exposed to sawdust Motor screeched, clunked then went dead.
Throttle clogged w/ debris, cleaned w/ air compressor. Motor now continuous loud grinding. Sent to manufacturer in Sask 6 wks ago & still no update.
Am suing person who operated power saw for negligence; need as much info as possible re: sawdust damage to equipment of any kind

Yeah, I seen a man go past me on the canal yesterday with 1 of them and his bike was creaking and cracking and squeaking

Hub damage from sawdust.
Have Swift step thru 2020. Motor slightly noisy, but since Sawdust exposure, ++ noisy. Send to Biktrix 6 wks ago, still no update. Throttle also clogged by debris, cleaned w/ Air compressor.
Appear as you (prior to sawdust even) noisy motor, sticking throttle + unpredictable jumpstarting of motor. Almost killed me once

I don't understand how sawdust could get into a hub motor. Have checked the chain maybe it is clogged with the saw dust. BTW what do you think Biktrix is going to do for you?

sawdust not prevented ingress by IP65 ‘dust tight’ 6 rating (5 is water protection level) as stays airborne:

System not allowing more screenshots.
Final display would have outlined sawdust’s ability to ruin fine finishes @ specified sizes.
SAWDUST WAS DELIBERATE: person operated power saw table to which bike locked during 2 day absence, no effort to move/cover bike w/ sheets/garbage bags in abundance everywhere. Table operated in car garage (confined space) w/ no ventilation.
WHAT I NEED: Source to analyze motor.
Yesterday Bixtrix provided pics motor ++extensive damage, irreparable. Not their policy to ascertain cause. Warranty declined. Intend sue for negligence. Need expert opinion.

In summary, sawdust possesses unique characteristics allowing it to clog the throttle, plus enter the motor via airborne currents & exert damage due to unique physical properties likened to ‘shards’ & ‘barbs’.

Following sawdust exposure motor screeched klunked then quit. Mechanic detected throttle clogged w/ debris ~ prevented engaging in OFF setting ~ detected by bike’s computer ~ disabled power supply. Treated w/ air compressor.
SAWDUST WAS DELIBERATE. table saw operated while bike locked to it during 2 day absence, no attempt move/cover bike. Took place in confined space w/ no ventilation
Bixtrix had motor >6 wks Yesterday sent pics extensive damage irreparable not covered under warranty Not their position to determine cause
Bike swift 2020 400 km @ time damage No sig rain/dust exposure
Intend sue for negligence
desperately need: source to analyze motor + info Sawdust Damage electric motor any type
IP65 doesn’t cover sawdust…particle size 0.05 microns remain airborne…IP65 only prevents ingress dust gravitating out w/in 8 hrs.
For detailed info re: IP65 + sawdust check threads/posts

Dont understand the question. Your assessment may be different than the mechanic. I wonder how any dust can get into a sealed emotor housing unless there are vent holes. Worstcase you are faced with a new motor or gears. Next bike, no vent holes.

A lot of hub drives aren't waterproof there water resistant so not only can water get in but dust as well. There are a few videos online which show you how to waterproof your hub drive, but this involves taking it apart and painting the insides with red oxide paint.
