I love my XF770 and it's extremely good value for money - BUT I do not find the seat or handlebars high enough for me despite what various websites say. I am 6ft 2 inches tall. I have added an extender to the stem post and an adjustable angle stempost on top of that, plus the seat post is at the absolute maximum. I have had to reroute some of the cables to allow this. I would suggest it is not suitable for anyone over 6ft tall - unless you are willing to make some adjustments.

Easy to set up ( basically just unfold it). Easy to handle and ride. Perfect for me and I am a 62 year old woman!!!!

Watch your distance. 15 miles goes faster than you’d think, especially, plan well ahead if it’s a round trip. Still, through all that, I love my bike.

I researched a lot and for me, ths had the most bang for the buck. I will be using it mostly with my camper. It was boxed and packed.well. Absolutely no problems or adjustments needed.

What an amazing bike the XF770 is! I’ve had it three weeks - a definite learning curve but I am loving it. When I purchased it, the XF770 was not listed on the Cyrusher website. I got in touch with them and was able to order it with a 2 month wait time. So glad I was patient and didn’t go with the larger model. The XF770 is right at the point of being almost too big for me. The point is, Cyrusher, please keep the XF770 or something similar for smaller people!

I am a newbie when it comes to ebikes and have been riding the XF770 for a couple of weeks. This bike is used in my neighborhood (mostly flat and some rolling hills) for exercise and enjoyment

for some short commuting or errands this is perfect. Update It's been over a year now and our bikes are still working great and hold good charge. Great experience!

It really is fun sensing the assist kick in for the first time and feeling like you can tackle hills that you used to avoid. The charge lasts for a good long time and the controls are pretty intuitive.

Cyrusher is the best value e-bike , as it has more features for the price. Riding comfort is good. Shipping was about a week and the bike arrived well packed in a carton with plenty of foam to protect during shipping. I have already put 300 miles on it in 3 weeks and no issues or problems.

I'd been looking at getting an e-bike for quite some time, as I'm getting old, and pedaling up hills hurts a lot more now than it used to 30 years ago. A friend of mine recommended this one to me. The bike itself is pretty sturdy. I bought it mostly for getting to and from work in the spring/summer/fall, it's 8 miles away, so I've been doing 16 miles a day. The pedal assist is kind of really awesome , but it's perfect for me. the price.

Like the style, look and feel of the bike. Rides well and took about 1 hour to assemble... then I looked at the directions! LOL Got it all correct. So, I'm glad I bought the bike!
