None. It's a great bike, I love mine.
The Amiti is the same bike, but painted for the women of the world. 👍

BTW, I discovered a new feature on the Amiti, quite by mistake.
The two front lights, one circle led on the stem housing, and a LED headlamp mounted on the fork brace - the latter has a switch on it, one way it lights up, the other the led circle light lights up. So I turned it on the other day and couldn't get the circle led to light. WTH. So I took it all apart thinking it was the switch, which did not fix it, finally ended up just putting it all back together and back on the bike.

Low and behold, it has a ambient lighting sensor - during daylight the circle light will light up, and after dark the headlamp lights up. I wonder if that's in the manual. 🤣

Really nice feature...lighting for dummies. LOL

I purchased the STA frame and am really thankful I did. It has saved me from a number of stupid dumps and at my age any ground contact is bad. Get over the teenage stimaga, you know it’s a better choice.

Thanks, no concern about appearance. I presently ride a RANS crank forward so gave up worrying about image a long time ago. My bigger concern was strength of frame and whether the frame was designed more for a female anatomy. The two replies that came back, yours included, put those concerns to rest.


I don't notice flex but I'm running Big Apple tires with no lock-out from the standard mediocre fork suspension on a Explore E+ 4. (So I'm forgiving front steering to be a little lazy.) I'm swapping the front fork with a 29" Air/Coil MTB fork with 80-100 mm travel. Strangely ,I'll really going to appreciate locking out the fork suspension for most of my riding. Thought about a solid fork but I still want the flexibility of a decent gravel road suspension. Who knows probably overthinking the whole thing because riding weather is still weeks away and am self quarantined for a couple weeks anyways.

I can tell you the Giant bikes are less wobbly than the old Specialized Roll.
Going to try to get out on the mtb tomorrow. We walked my regular loop today, ran 'tiny trucks', about 4 miles. And our favorite tap room opened for a few regulars. It felt like a speakeasy. Knock on the back door, front windows are papered out. It's really weird here, but a bazillion people out on the trail. As busy as I've ever seen it. Lots of cute dogs too.

These are 1/10th scale lipo electrics, yes they ran for over 3 hours today and 4 miles.

While we have a couple of threads going on this model, they were for specific problems/questions, so I thought I would start a new one, talk about my 2019 +3, and invite comments discussion and questions on both the +3 and +4 US models, for owners and would-be owners.

I've put a couple of hundred miles on so far and really like the bike. There are way many more things that I like than things I don't. So I'll post a few points, a pic or two, and open this for posts/discussion.

I'm 62, 5-10, 180lbs
Avid rider, although never as much pedaling as I liked, spent much more time on motorcycles. Now the latter are all sold due to age and risk, so getting wife and me ebikes opened up a whole new entertainment opportunity for us. We're having a ball!

Comfortable - I changed out the stem riser to a 45* - 110mm reach. Substantially improves the stance for me.
Good power assist - I mostly ride at level 3, sometimes 4, and occasionally 5 if I'm tired, a steep hill, or just being lazy. At level 3 I'm getting somewhere around 45-50 miles of range.
Seat/Saddle - is more comfortable than I thought it would be. Not changing it yet. The 2020 model has a different saddle.
Ease of riding - at least as easy as my pedal bikes. I really like a 700c/28-29" wheel bike, so this was a natural.
Brakes - the 19 model has Shimano hydraulic discs - the 2020 went to Tektro hydraulic. The Shimanos are flawless.
Color - for 2020 Giant went the a satin black with blue accents. I got one of the last '19's and really liked the bronze-gray color with hyper-green accents.
Giant Ride Control App - this is a way cool feature that connects your smartphone to your sync-drive power control for all ride data, speed, odo, battery level, assist fine tuning, and GPS mapping. It's a little balky setting up but once you get it dialed it's really slick. I use mine on a iPhone 6Plus with a ROAM mount.
Battery integration and design - all good. I think they did a good job on this, and I like the swing-out removal feature.

The fork is really minimal for a suspension. Here again, the 'updated' 2020 model doesn't have a lockout, the '19 does. But you can dial the preload in enough to make the '20 one really firm. IMO this isn't as much of an issue on a ebike since the pedal power loss from suspension is made up for with the e-assist. It's really nice to have something up front though, for rough roads, driveway ramps, expansion cracks, uneven pavement. I don't know how much offroad mine will see...probly not much. LOL
Shifting - I finally had to do a tuneup or adjust on the derailleur - it wouldn't shift up to higher gears, then would clunk into another gear or two when ramping up pedal pressure with the assist. There is no motor shut-off for shifting with the Yamaha mid-drive, so you have to let up or it clunks pretty bad on shifting. Once I got my derailleur adjusted shifting became effortless.
Tires - I wasn't impressed with the relatively skinny 'crosscut gravel' tires that come with the bike. Same for 2020. Right away I changed them out for Schwalbe Marathon 47-622's, pretty much the same size as the stock tires. They were fine, if not a little hard unless I aired down to about 35lbs. So I decided to get Schwalbe Big Apple tires in 60mm, or 2.3 inches wide. They're beautiful. Interesting that the rear rim is 25mm wide with eyeleted spoke nipples, the front is 19 with no eyelets. They really beefed up the rear wheel for 'E' power.
There is no charge port for your phone.
There are no lights, not even front or rear reflectors. I'm researching my options here, but rarely ride at night anyway - I can see well after dark anyway.

Later I'll post more pics, and a list of accessories and changes/upgrades I've done on mine.

So without further ado...here's a pic of mine with the new tires, and now I want to open this up for more discussion, question, and comments.

The bigger tires just fit:

Just got it here, has the Marathon 47-622's:

Just a quick note. I have a Giant Explorer, step through, and my Dealer showed me a Liv which I bought for my wife at the same time I bought mine. Made by Giant and almost identical but with some good upgrades like lights and a larger front disc. If you're looking at Giant, look at Liv.

On the taillight issue, I've been using a Garmin Edge GPS device to track and record my rides for quite a number of years and will probably continue to use it when I get an e-bike. This year, I added a Garmin Varia radar taillight and it works great. I get a warning tone and am able to track cars approaching from the rear on the Garmin display; it picks them up before I can even make them out in my mirror. As a car gets close, the taillight gets brighter and flashes at an accelerated rate. Nice product!
I lost a friend last year to a driver who was texting. He was a seasoned road cyclist. Bought the Garmin Varia soon after this. It saved my life a couple days ago. To me, for $200, it is a must have not an accessory. 👍🏻

I had fogotten that we got a LIV Amiti as well since then. She really likes it. 👍
and my better half chose the Liv Amiti over the Como today- no we both couldn't have specialized products, but we are opposite on most things and that seems to work for the past 40 years, the "virus" is good for some - our bike shops are practically sold out in our neck of the woods . . .
