Hey people. Nice to find an ebike forum!

I've got 5 Genze's so I know a bit about them but Genze is my only ebike experience so clearly I'm no ebike expert.

Genze has two series of ebikes. 100 series and 200 series. The 100 series is a bit more basic and lower price. 200 series has more bells and whistles, an app whatnot. All my bikes are 100 series.

There are two frame styles. The 101 (ladies) and the 102 (mens) although with my poor old legs a step through might be nicer. There are 3 frame sizes. 16", 18" and 20". The ladies style doesn't come in 20". The seat extends on a very long post but the handle bars are fixed in place and don't extend.

Of my 5 Genze bikes, I can say there are 3 different "generations" in the 100 series. This isn't official from Genze - just my observation based on my own purchases and looking at the web site.

The oldest has a down tube that has square edges. The battery is a boxy as well and a bit wider. The controller LCD screen is vertical. All of this series have a 250w hub. The bikes are all silver.

The next generation in the 100 series (I have 2 of these) have the same 250w hub. The LCD panel is horizontal. The down tube has rounded edges. The battery is longer and narrower but the same weight and power as the older series. There may or may not be a USB port for charging cell phones. The bikes are all silver.

The latest (last?) generation of the 100 series (I have 2 of these) have a 350w hub. The battery is identical to the 2nd gen. The bikes can be either flat black or silver although most seem to be black.

The bike has 5 levels of pedal assist and a twist throttle mode. Yes I know that's illegal some places. But I guess Genze owners are rebels.

I would say the 350w has more power and more pick-up and more ability to haul my fat ass up steep hills but the 250's are just fine too. On the straight and level they all max out at 20mph. Range is decent. I can easily do a 20 mile trip using a combination of pedal assist and throttle (I'm lazy so let's be honest and say mostly throttle) and I still come in with 30 -45% battery. I just did a 100% full throttle run 20mph all the way to home depot and back - 8 miles round trip - I came in with 50% battery left.

I added a basket and some saddle bags to my bike. The extra weight might cut into distance but worth it for me. To add the basket I had to move the LCD control which Genze really doesn't want you to do. I tried to post a pic of the bikes and links to the saddles and basket but that's not allowed for new members to the forum. Sorry... maybe later.
