Hello everybody!
This story, of course, has its beginning. And it all started with the fact that, while thinking about what to do in the next off-season, I missed the excellent Giant Revive S7/3 option on Avito. While I was thinking: it is necessary / not necessary, while I wrote to the seller – the bike has already sold out and left for St. Petersburg, but not to me. Why Revive?
There are several reasons:
1. Two bicycles of the same model in the arsenal (RobBrady DB0 EZ) is too much.
2. I wanted something different. On the one hand, it's not a unique custom design or another masterpiece from a design studio, on the other hand, it's unusual, but serial. Revive, just right.
3. During the 2021 season, I realized that I no longer want to ride in a classic bike fit. It does not stick over the front wheel. And I'm already so used to chopper landing that I don't want to change it drastically.
4. The engine is "released". The carriage TongSheng with a torc sensor didn't exactly catch on with the ladies' roadster, but after four seasons of our "electric era", we decided to make at least a couple of muscle-powered bikes. Since the roll of the Czech CrossCity is simply stunning, it fell under the "reduction".That's where Giant Revive, which I noticed a long time ago, surfaced. I must say that this bike is very peculiar in absolutely everything: the layout, geometry, equipment, and technical solutions do not seem to cause awe individually and are already familiar somewhere, but their combination is something new. Although they were produced in the first decade of the 21st century, today it is still very original and interesting.
There are not many of them in Russia. Such a bike is not common on our bike paths. The unusual appearance, although it attracts attention, immediately scares away. And if someone inexperienced asks for a ride, then the potential user will definitely be lost. Only those who drive a chopper, a cruiser, a limousine or a lowrider will feel comfortable on it. The rest, alas, until the first turn. That's why there are few of them in our country, due to the lack of demand. I must say that there are a lot of them in other countries. Germany, the Netherlands, the USA, Britain, Poland, that's probably all the countries where they are more or less sold at auctions and flea markets, at reasonable prices, by the way. I found my copy in Germany.
This is a story that deserves a separate narrative. In short: the Germans are completely unwilling to bother with the preparation and dispatch of goods. "Come, pay and pick up" is usually the limit of correspondence. But they respond well to the offer to "drop the price." There is no need to bargain for a long time, but if you offer a price 50-70-100 euros lower than stated, they agree. Thus, the Revive purchased "there", together with all invoices and deliveries, costs about the same as in Russia. On the condition that we don't have them, but "they" do, and we can still choose from something. Of course, there are all sorts of "subtleties". For example, TC in Germany will give a hundred points to our TC and Mail combined. The bike, which was located 100 km from the warehouse, drove to it for 10 days!! In German, pedantically, but slowly, 10 km a day.
Well, okay. Enough of the lyrics. It's time to get down to business.
Giant Revive LX, probably 2006.
The equipment is standard. Frame - drain, vilset (20*1.75) - drain, dynamo in front, Shimano Nexus 7 in the back, roller brakes - drain, light/size 6B - not drain, pedals - not drain. There is no stock speedometer. What I would like.
I plan to keep the intervention to a minimum.
1. The defect is our EVERYTHING. Disassemble/clean/ lubricate. Out with the rubber and cameras. They probably haven't changed since 2006. Nowadays, cameras are almost not installed with bicycle nipples. I don't want to carry an extra hose, much less a pump. There seemed to be a Schwalbe with whitewalls and cameras in the storerooms. So I'll put them on. The lighting fixtures, the ones included, are not regular and don't seem to be bad. They are powered by dynamos. I'll leave it.
2. Install the engine, of course. After studying the "collective mind", I decided that the released carriage driver was what I needed. It is not heavy, it works in a comfortable 48/15/500, there is a battery, the mileage is not high. The nominal value is 500W, stitched to 750W, this is the maximum mode for filling the motor and I practically did not drive in it. The mileage I got from this build on a 60+ km, and the speed is 40 km/h.
On 20 wheels, the speed will drop, of course, but 30 km/ h will be quite enough.3. I'm not going to change anything about the design. I'll just replace the seat and put another steering stick. The rest is just small things: grips, pedals, a trunk bag, mirrors...The result should be a two–wheeled, comfortable and lightweight (by e-bike standards) carriage for leisurely walks and trips to work. A compact replacement for my choppers. If the eldest daughter likes it, I'll give it to her. Let him ride.This is how it looked right after purchase:

Judging by the photo, the condition is cheerful, although traces of exploitation are noticeable.The first thing that will be replaced are tires and cameras. Not only because they are old and have a bicycle nipple on the camera, but also because the storerooms turned out to be brand new Schwalbe roard cruisers with whitewalls and the usual auto clips on the cameras.

At the same time, the steering wheel is "assembled", since the stock steering wheel is not suitable for equipping it with the necessary equipment. Firstly, the welded panel on top of the standard steering wheel was not equipped with a stock speedometer, and secondly, it does not allow the engine controls to be placed on it without serious interference with the design. In addition to the steering stick, the grips (leather for now, then I'll put rubber on), brake handles and shifter have been replaced. The mirrors left over from one of the previous projects, I think, will fit perfectly into the exterior of the structure.

Hurray! A bike arrived. Everything is as shown in the preliminary photos, no more, no less. Preliminary inspection/defecation.
1. The planetarium is not 7, but 8 speeds!
2 The front bushing is tightened.
3. Tires and cameras are ALL different.
4. The chain, brakes, steering column, and rear suspension are lubricated and uncomplicated.
5. The grips are barely alive - in the furnace.
6 Saddle with a barely noticeable small crack (I'll fix it).
7. The headlight (and speaker) are working.
8. It is battery-powered and works.It's COMFORTABLE to SIT, kapets. Almost like a chopper. I even thought maybe I should leave it as it is and not farm the engine... But later he "came to his senses" :).The rims are double and very high quality. The tires and cameras have already been swung. The steering stick, too, by the way.The steering wheel, adjustable in height and angle, is generally a masterpiece. This is the first time I've used it.Well, that's about it for now.
The rest can and will come out during operation.Tomorrow I'll deal with the front hub and the engine.
 
That's the first, if not the MAIN, trouble.TongSheng TSDZ2 did not fit this bike. The drive star and chain will not be able to be laid too far from the axis in the body of the right pen of the frame.

Medicines could not be found "head-on".
1. The carriage cannot be "moved".
2. The "plate" star, such as on Bafang HD, will not work without dancing.
3. I WILL NOT cut the frame.In general, those who are thinking of introducing Tongsheng on this frame, take note of the information.Well, that's okay. The engine will return to City Cross and will work in tandem with NuVinci.
You may have to buy a Bafang and install it.

After reviewing the network, our collective mind and the foreign one came to the conclusion that it might be too early for me to write Dongsheng off as a "hopeless" option for Giant revive LX.
There were offset versions of the leading star in Italy (expensive, kick-ass) and on Luna, in principle, they are ready to contribute (even more expensive). While the issues are being resolved "there", I'll try to make up my own.Of the affordable ones, only Bafang makes offset stars for its engines, ranging from 32T to 52T.
I found a standard stock 44T in the ZIP. Since I'm not going to use it anywhere, it's going to be used for experiments. Her offset is pretty decent, about 13-14mm, so there is hope.What do you need:
1. Drill 5 holes for the Dongsheng spider BSD.
2. Cut off the excess (the inner radius of the Bafang fastener).
3. Try it on and be happy/sad.It's already lit up. Tomorrow I'll go to the garage for a grinder and I'll try.
Hurray!! It worked!
In my case, the "toad" that was strangling me about the special offset star kits (cost from 90 to 150 euros) eventually allowed me to adjust the star from Bafang to Tongsheng.
The chain has gone into the casing and feels great there. It remains to choose 1mm so that the chain does not touch the plastic of the motor, but these are small things.

The bike is ready!
It remains to wait for the new pedals and fasten them.The test characteristics of the engine are almost identical to the calculated ones.
Weight: 28.5 kg.
The controller parameters are set to 720 Watts at the peak (15A at 48V).
The leading star is 48T.
Speed:
1 gear - 15 km/h;
4 gear (direct); - 29 km/h;
8th gear - 47 km/h.
In general, it will go 35 km/h for sure, but I don't need any more. Not a cannon/race, after all.Accessories: a bag on the trunk, a handbag on the back, a tool/pump on the left side of the frame, music on the right side of the frame (Venstar S400, 16W).
