Re: Mrazek RevX superlight electric freerider

Revx ... I appreciate you taking the time to write to clarify things from your side.

Speaking of your bike and manufacturing output ... what’s the waiting time for your bike right now after a payment is made?

Re: Mrazek RevX superlight electric freerider

I get it .... but, you need to understand the language to be able to tell, whether this looks like a fake or not. Surely, there are issues ... but I find it too hard to believe how such a bike would be let go out of any manufacturer. Anyways, there's some bad blood between Mrazek and the company who...

Re: Mrazek RevX superlight electric freerider

I speak the language of the narrator in the video, so I am not just reading caption....it’s either satire, a very pissed off customer or very badly assembled bike ..... you pick. If the bike was truly received in this shape, I would already sent it back long time ago, without riding it.

Re: Mrazek RevX superlight electric freerider

Color me confused ..... So czem.pro makes Drill-One ... aka Revx .... czem.pro signs a distribution deals with companies around the world, incl. cpd.direct for US .... but the Drill-one is a copy costing the same money and looking from the pictures, like very good copy, of the original Revx?

Re: REVX Manufacturer Info Questions and Answers

Very cool. Loving the bike design, quality and specs. I am hoping to swing my legs over one when in CR during summer.

Any plans for some sort of a distributor for North America, so shipping is made easier for people living there?

Good luck with the bike.

Re: RevX bike

I've been in touch with Bob and if I,m correct the battery and controller are worthy of much more power, were sat on the fence about needing more power at the moment as just like all powered vehicles there is a sweet spot which just suits, from what I read on FB there's some ultra fast Rons about, ...

Re: Specialized Levo vs BBSHD

That goes on the positive aspect of buying a $5k+ ebike. - Great handling characteristics - Great weight distribution - Balanced Good All for multiple thousands of dollars.

Re: Noisy Electric Motion 5.7

OK, here’s what I would do .... first off, does this knocking noise occur when the bike is on a stand with both wheels off, just twisting throttle. Yes or no? If no ... describe better the noise as to when out when it happens. If the knocking happens even on a stand, I for sure would have taken the ...

Re: Noisy Electric Motion 5.7

I have the same bike, but not the same problem ... but you are not the first one, who would experience a premature motor bearing failure. This is more-less budget motor so I guess they used cheap bearings not the top ... see this thread below on AR forum .... https://advrider.com/f/threads/electric-...

Re: 2016 Electric Motion EM 5.7 Upgrade

The electric clutch is only start stop switch and doesn't really do the job that a clutch does with a convential trail motor. I have a GASGAS txt-e where they mounted a electric motor directly to a gearbox with a convential clutch. Are you referring to TXE model? Which country have you taken delive...

Re: Quick question about a contactor

Not sure why would say that ... Of course I have looked, even at places you recommend.

Re: Quick question about a contactor

I have a room in the amps department ... but I have no room on power line voltage department. They claim 36V contact voltage as per specs ... and my system operates at 48V nominal .... so that's why I am asking here ... plus I have not seen other DC contactors where the manufacturer states two volta...

Re: Quick question about a contactor

Thanks for your reply. So it is a bad idea to connect 48V battery to a contactor which is rated for 48V coil voltage trigger, yet only for 36V contact voltage (this is the only contactor which I found actually states a contact voltage or where it’s coil and contact voltages are not the same .... I g...

Quick question about a contactor

What will happen if I connect 48V battery pack to the below contactor? The battery pack amp rating is well well below max cont. amps of the contactor?

I get the cell current limitation .... But isn't the series connection/joint have its own limits from design/material stand point? The way you are describing is that the only limit is the cell rating itself??

Ok. They just did not look like a power sports company to me, looking at their website. But perhaps they are.
