Euybike S4 Long Seat

Good:
1. Perfect size to finally stretch out and adjust position on the fly without worrying about the groove between seats.
2. Fairly easy to install; the six threaded studs on the seat were misaligned by about 1/4", but it wasn't difficult to persuade them into place. Reminder that the stock passenger pillion uses 5mm Allen bolts, stock driver's seat is 10mm nuts. New seat is 10mm nuts. A cheap open-end wrench is included as are the six nuts. Deep socket is probably best because the studs are long.
3. Quality & construction is good - comparable to the stock seat.

Bad:
1. Definitely firmer than stock seat. I find this can be managed by the extra ease of being able to adjust position on the go. Euybike's description does say that this seat is firmer - truth.
2. Personally I like the saddle color of the stock seat.

I think this the seat that should have came with this bike. Awesome seat very comfortable.

I'm not sure why euybike.com is calling this seat black when clearly it's dark brown and now it's out of order
update: giving this a five star for customer service they always respond quickly and take care of customers thanks again euybike.com

Although the brown long seat with the flared tail doesn't show available to order on the website, I was able to order it by contacting customer service first. The customer service has always been first class as they are quick to respond. I love this new seat. I replaced the shorter seat that came standard with this longer seat. It is easy to install and the screws aligned perfectly. It makes the bike look sportier and the ride is more comfortable as I am able to sit further back.

Great customer service and fast delivery
