  • Best ebike period in this class
Color: Grey Style: Upgraded Speed Version
Two words, SUPER TANK. I had another brand ebike and went with the K6F Pro 40+MPH upgrade. Game changer. I researched sooooo many ebikes out there and finally decided on this bike. A Tank. Aggressive look. Very fast. Might as well upgrade to the max. Turn signals, rear brake light, 8speed Shimano ALTUS gear. Definitely has to be locked up in public because you can power this thing up without the key. Just use to remove battery. Very fun to ride. Comfortable too. Very heavy but solid weight A must buy with 35Ah battery. Long range. Cons: defective battery. Only 19mi. No replacement batteries in stock. Sucks... Customer service was excellent. They gave me a new battery. Already put 1,009mi on this bike. NO ISSUES. It was worth the wait for a new battery. ... show more

  • Solid design, comfortable, fast, and premium components.
Color: Grey Style: Upgraded Speed Version
I purchased the K6F with the 35AH battery. The bike is 100+ pounds, very sturdy, well packaged and assembly was fairly straightforward. The trickiest part was aligning the front brake disk between the pads perfectly. You just need to be patient and persistent; once locked in, it stays put nicely. The only other gotcha was the 16mph default speed limit; and I wanted a top speed of 30mph. It takes a little bit of digging into the Key Display menu to find the SP (speed) setting. I set it to the max...65mph...not because I'm crazy enough to go that fast, but because I kept running into the 16mph limit whenever I tried to set it. Finally I figured out that in addition to increasing the SP setting, you need to advance the pedal assist setting to 2, 3, etc.. in order to increase the max speed. I was keeping it at 1 thinking it was for pedal assist and not max speed. But it turns out the pedal assist selection also controls the max speed! I think they should make this more clear in the manual, but otherwise everything else was straight forward. I love this bike, its a real cruiser; low slung with a cushy ride from those fat tires and nice suspension. And the battery lasts a long time...at least 65 miles with very minimal pedal assist. I'm sure it would go further, but I'd have to run the battery until the BMS shuts it down and that would leave me stranded. :) FYI, I bought the following accessories... 1) Rear rack - https://www.amazon.com/dp/B0D59HZL45 2) Rear view mirror - https://www.amazon.com/dp/B0DT3YF764 3) Heavy duty lock - https://www.amazon.com/dp/B08M6HST7G All three were chosen based on ChatGPT feedback. BTW: The bike looks gray on the Amazon page, but in actuality it's darker...more of black ...it looks great IMO. I liked it's color even more when I got it. It gives the bike a more competitive serious look rather than a toy look. But that's just me...I like the more colorful bikes as well, but understated is more my preference. ... show more

I have purchased the gray version of this bike as well as the blue and have ordered the gold now also, these bikes are very powerful and very fast very responsive. I read a lot of reviews of people saying they don’t have brake lights or turn signals, but if you buy the 40+ mile an hour upgrade version of this bike, which all three of the ones I have purchased are they do come with front turn signals and rear turn signals, plus a brake light very awesome bikes ... show more
