Bottom of headset is pain in butt to match with forks. Major problems. figuring out. The bicycle shop fixed my problem with the right parts.

I came from the bike industry and built dozens of Mountain Cycle and Intense full-suspension downhill and cross country bikes, and trust me when I say that the excellent customer service that Anne of NBPower provides is worth buying the fame on it's own. Here are the other details: Issues... the seat tube is a bit stiff, so only a quick release clamp is strong enough to keep your seat post from falling, and you really have to winch that hard to get it to set right; there was one nut that keeps the side plate on that I had to tap; the rear stays were about 1/4 inch too tight for the back hub, so you will need help to remove it at first, but overall, this was an easy build.The effective top tube length is 34 inches at the start, but the single pivot reduces that when you add the sag of the rear shock (as the post comes down, the head tube and rear hub get closer together); the bottom bracket is VERY high so if you are under 6 foot, don't buy the 4 inch tire version. I'm 6' 5" and I can barely stand clear over the top of the bike. If you are under 200 pounds you might want to get a 550 spring for the shock to make sure that the frame sags enough to make the geometry to work properly. At this point, I have the bike pretty well dialed in for my size and I do love riding it. The rear shock Anne suggested is SO plush. Outstanding shock for the money. Even my long-time friend who owns a bike shop was impressed with the overall ride. SO smooth. It's a bit funky and heavy, but I love it and would definitely suggest it to others, and already have.

Snapped in 3 pieces after a year and I only weigh 150lbs. Be careful…

Solid frame. Built to be easy to put together with the right parts. Only one small annoyance, was kind of hard to get screw in the hole for the lower part of the rear shock, but not too big of a deal; was an easy fix.

I purchased nearly all of the components for my eBike from NB Power and everything has worked as promised. I had to do some fabricating myself but the bike works well overall. They have excellent customer service and can help with troubleshooting if necessary. I am very pleased with their products and will continue to use them again in the future!
