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. What makes me wonder about, if something breaks on the ebike, who actually fixes it. The local bicycle store mechanic or do th...

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. The contactor I asked about was given to me ... but since I looked the specs up, I noticed something I have not seen clearly posted on any other sites. That's why I ask, how does it really works ...

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??

I don't see a series connect Amp rating on the website. Somewhere I read that it's 50A per P module ... but it didn't say how many P configuration??

Re: 2018 Mrazek RevX superlight electric freerider

Ok. They just did not look like a power sports company to me, looking at their website. But perhaps they are. I hoped they would rather end up being distributed by a dedicated electric bike company, but I guess we will have to see what these guys will do with it. Kuberg ended up doing their own thin...

Re: Need Help with 2016 EM trial bike; Throttle issues

I have not checked what the measurements are when on the bike ... there’s no easy way to get to the exposed wires. Will have to see of I can get the probes in there into the little bracket where the wiring enters the plastic housing.

Re: 2018 Mrazek RevX superlight electric freerider

I am very familiar with the product and Bob's FB page ... the issue is that to ship it to NA as a single bike is just too much hassle and cost. So it would be interested if somebody picks it up. Let us know when you find out.
