BOSCH!

Nice bike
I purchased this e-MTB for my gf so she can ride with me. I have an human powered MTB. The weight does not seem to be a problem and it’s playful in the mullet form. With 4 modes, you want easy, use more power. You want a workout, use less power. My legs still feel like jelly when I finish riding. I’m not fond of the magura brakes. I’ve always heard great things abt the brand, but I just cannot get them to grip very well. I have sram brakes on my 3 other bikes, YouTube was helpful. I have ridden it more than she. lol Go figure. It’s fast and fun. I can go 2-3x times further burning more calories and love flying up climbs. The suspension is excellent. I’ll be swapping out the transmission to AXS. Overall good fun bike.


Wow, this bike is AWESOME!
I've been riding a Polygon Siskiu T8 for several years and I love it. When I realized the Polygon Siskiu TE-N is basically the eBike version of my analog bike, I went for it! Riding eMTB is a totally different sport but it feels much more familiar on a bike with similar geo to what I'm used to riding. The shifting needed a little work out of the box, but otherwise the bike was in good shape for riding. I love Polygon bikes and their eBikes don't disappoint either. This bike rides amazing and the value for cost is unbeatable in my opinion. I highly recommend!
