Any Opinions on this bike ?

[Elecman]

Read good things on this forum before about other 'Mosso' bikes sold on eBay.
Looks like a Chinese bike being sold from Europe.

This one is a mid-drive rather than hub motor.
Not sure what the motor is, it says 48v motor and 36v battery ?

Hi Elecman, i think i asked the same question last night in "what do we think of this" had some interesting replies

checking the seller's feedback: he sold 3 bikes in the last 6 months. One is refunded due to product mixed up, net sold: 2.
He hasn't sold any of the Mosso BBS yet.
Re 36V: it looks like a typo. Still, I'd like to see a close-up picture of the motor that it is correctly labelled 48V 25A. I'd ask questions also about the battery continuous rating and cell brand. Chinese factories usually limit the bms to 1KW because of fire hazard. This means that you won't get more grunt with the 48V than with the 36V if both are rated 25A. It's better to run the 36V 25A with 36V 30A continuous Samsung cell battery than 48V 25A with 48V 12AH Chinese cell battery, less fire risk.

Cheers for the replys, I will look at the other thread as well.

It says in the ad that it uses Samsung high discharge cells, should we take that with a large pinch of salt?

they probably tell the truth but does not change the fact that running at over 2C carries fire risk. A motor labelled 25A will peak at much higher than 25A. The supplied battery is rated 48V 12AH and should not be used at more than 24A. Beyond 1KW, I think the battery should be designed by specialists and should use LiFePO4 NCR cells.

So it could be dangerous? God this ebike buying can be such a nightmare

sorry to be sounding negative.
TBH, I'd like to be able to climb 15% hills at 15mph but speed above 25mph scares me.
