Your Creation's Before & After Pics

[Dee Jay]

I've slowly added so many things on this Giant Revive since I bought it early this year, hence the series of pics. Hope I'm not taking up too much space.

I didn't know the attachment order was going to be reversed. Too lazy to fix it : (

a) Before

b) 408 Journey Kit and bags

c) 4011 at the rear, Bell Cocoon Child Seat, and SLT Transmission

d) 36v 9ah NiMH on upper frame

e) My son's protective padding, "Egg Prince"

f) Ammeter, voltmeter, PAS button, and on the PVC joint and pipe.. wireless cyclometer, 3 LED flash/headlight, and my Starbuck's Tall Crappachino

g) Not very stealthy, but not too frumpy either...

h) but the more I add accessories, the frumpier it gets

i) Dewalt packs in parallel

j) The Dewalt battery rack is secured over the NiMH Journey Kit quick release bracket and can be removed for NiMH battery use.

Next project... my wife's Revive so she can keep up with me

Updated shots:







I saw an old guy riding his bicycle on the lower bike path while flying his kites. It was going to be a great shot and I was intent in capturing it long with the sunset and my bike. Unfortunately a little old lady who was about walk down the steps behind my bike STOPPED (at the rear of my bike) and stared at my bike for the longest time just when the kites entered the frame. She knew I was taking pictures, she was just being a pain in the ass. There a lot of people like that here, sheesh . . . No worries, I simply deleted her and pasted a portion from a previous shot. It's hard to tell . . . notice the lite spot on the very end of the triangle bag?

That's awesome DJ.

How does two motors go compared to one?

 

[Dee Jay]

Thanks, Mark!

I'm planning on distributing the Journey Kit so part of the reason for two motors is so I can show two motors to my customers on one bike. I haven't done controlled tests, but as far as handling, the motors aren't that heavy, it's the NiMH pack that's a bit much.

Both motors serves their purpose, and serves it very well. Compared to the 408 by itself... the 408 has good torque, especially on 20" but still wastes energy on hills, I think. With the 4011, it can get my son and me up a pretty steep hill when battery is freshly charged. As soon as I figure out this Dewalt 20 kph problem, I'll learn more how these are with robust power.

They don't run at the same time, but I'm curious to know what it would be like if I somehow found a way to transfer power smoothly between them. I'm guessing the "sweet spot" where they're playing nice together would be great climbing hills at a good speed. As I mentioned in another post, the weight of an extra motor is negligible once you get going. Besides, whatever energy I waste with the extra weight, I'm sure is made up by each motor helping each other in speed or torque.

Finally get a chance to post my build. Still have some kink need to work out but it rides well right now. Battery might need to be relocated to that ridge on the frame.

Bike: Schwinn S60 Full suspension mountain bike - Front disk brake, V-brake rear, shimano rapidfire shifter. Flimsy aluminum frame is creepy when you hold up the bike. A light shake makes it wave. At high speed the bike feel like a rabid squirrel. Skipping at every pothole.

Motor: Crystalyte 408 with 48v-72v 35A controller, 7 speed freewheel, mounted in 26" wheel

Battery: 4 Dewalt 36V in 2s2p configuration. Kept in original shell, just tap into the tab using wires. People give me odd look when i lug around black bag with wires sticking out.

Comment:
The torque arm is connected to rear disk brake mount. Look really weak and is probably useless. Will make new one when i have time.

Haven't tried out the mud guard. But the way its mounted every time i hit a bump the wheel bottom out and hit the mudguard(fender)...rear.

Fastest i could get it so far is 32mph with pretty steep hill. No load speed is 40mph.

With the battery mounted so high. The bike corner like shit. With 66v the motor produce ample torque and no weight in front it skip around when hitting large bump. Must learn to let off throttle when hitting bump.

I've tried 84v and the controller would take it, but there is a high pitch hiss like noise so only ran it without load. Didn't try riding it. Might mod shunt to take 50A or so. Might help the bike hit closer to 40mph mark.

Try 40 pounds of offspring mounted on a rear rack in a light road bike. Terrible. And the thing wants to pop a wheelie when I dismount!

I have that same child seat as you do Dee Jay. Your pics make me want to try one of those low bikes. Where do you live?, those paths look nice.

Just by looking at these pics without a rider on the seat, the 20" wheels gives an illusion of being low-rider like a true recumbent. But in actuality, the rider can sit just as high as a mountain biker, if not higher since the seat is adjustable in height. The difference is being able to recline a bit more than the usual "comfort bike".

It took me several months to learn to relax into the backrest. I would like to recline a bit more and to achieve this, I came up with this crazy idea to use (this is what happens with too much coffee ) 26" front wheel with a 406 hub, though the difference between a 20"/4011 rear and 26"/406 front might be too much with no sweet-spot. This project will require changing the fork which is not difficult at all, other than that there will be no permanent changes to the bike. My trail and head-angle will increase, good for high speed cruising.

Which brings me to another whacky idea: a lightweight hydraulic piston under the spring shock to lift the upper frame for normal trail/ better maneuverability and balance on slow rides, then lowered for chopper like straight cruising. If I can't find a piston, I'll try to find a way to manually adjust the height.

I'm in a suburb in Tokyo Japan. There are prebuilt hubmotor bicycles here, some imported from China, but I maybe the first ebike hobbyist here. I get a lot of positive reactions from people young and old. But then there are haters too. A few young guys tried to show me up racing me with their disposable 26" bikes, little do they know that I'm going on a 19 km ride. With hills. Then I got people asking me how much it weighs. Cyclists here are so stuck on the idea that all bicycles have to be built with anti-gravity alloys...

Nevermind the spandex set...

I got tired of sitting on my crotch and wanted to sit on my ass so I chose the Revive for comfort. Soon, I'll be shooting for speed. In the meantime, I'd like to see other Revive owners try my ideas.

What do you guys think of my ideas? Suggestions and comments are welcome.

Hi volks!

This is my first ebike, with a 60volt configuration.

__________________________________________

Now upadted it to 72V with one more lead acid and now I have a top speed of 41km/h without paddeling. This rocks :lol:

__________________________________________

Next project will be 100 Vol with 6 Dewaltpacks 3s2p. For this I#ll have to update the fets and I'll probably need a full suspension.

 

[Arbiker501]

HI guys,

NEWBIE here but proud of my after bike.

She is a 700 cc touring bike. All steel .
The Kit is a BL 36. Using 7amphour slas. IT is a peddle first kit.

Hey dude... just wondering where did you get the battery / controller container from... coz it looks like a scooter box.

also did you do any modifcations to your wattsup meter? as these are rated at running at most 60v?

IT IS a scooter helmet box - rock into elizabeth st in the city dude,u should find one there.

hi, no modifikation with the wattsup, it works just like this.

 

[Drunkskunk]

be carefull with that watts up meter. Mine blew up at 74V. it was an instand death sort of thing, too.

That Yamaha is awesome

Motorbikes have never "done it" for me, but that's cool.

Needs more batteries though!

 

[Dee Jay]

Hi Mark, yeah that bike is da-hots.

I couldn't find any further info on it. battery? torque? top speed? matching motors? I'm sure it has some kind of electronic power distributor inside the controller allowing both motors to communicate digitally and help each other.

My idea on the other hand would be SLT: relays at the coil leads, not in the controller. The motors would not be drawing amps at the same time but simply switching at high speeds within the sweet-spot, just the same way spark plugs are distributed high voltage by a mechanical distributor.

Would be easy to just have two controllers and two throttles and just mix it up on the fly manually. Imagine a throttle on the right for the rear motor and a throttle on the left for the front motor... but this would be the same as using a manual transmission.

I want automatic transmission that depends on kph. high torque with the rear, high speed with front.

Just brain farting here, ~ phew ~ stand back :wink:

Woops, apologies for posting this in the wrong forum!

Needs more batteries though!

Yamaha is not about to mess around with SLAs. They know battery technology isn't ripe yet, until then it stays a concept bike. Once everyone goes nano, forget about it . . . hoo wee!

[Mark_A_W]

SLAs?

You mean people put car batteries on bikes?

In this age of Lithium?

Surely you jest!

(RC Lipos cost next to nothing these days..)

 

[Dee Jay]

Surely you jest!

That's just what I said when I learned about SLAs on bicycles

Surely you jest!

That's also what I said about my NiMH pack losing range!

Of course I jest, tee hee hee!

Since dewalt packs are still pricey, I'll give NiMH another chance but this time made in Japan, Yuasa NiMH pack and see how they hold up. Yuasa factory building overlooks my parking lot! One day, I had a handful of Yuasa engineers spying on me from their smoking section on their veranda. Didn't have time to chit-chat as I was on my way out with my DCR. The look on their faces was priceless.

I really like that helmet box as well. What is the brand name?

 

[jakun]

Hi, I've got it from ebay in germany. it's from gerda
you can search for:
"Gerda Touring Tresor Koffer schwarz 14 LITER"
the guys name on ebay is: radwelt-hawner
he has a shop.

Hi Guys,
I have been doing some research and development and have been reading your great posts every day very closely. One of the results is that I have build a fully stealth Ebike I think! See the pictures down below. Hope you like my conversion.









Some specs:

- Current Setup: 48 Volt, 20 Amp
- Vmax: 54 km/u
- Cruising speed: 43 km/u
- Max Power: 1,1 HP - 40 Nm
- Drive Train: All Wheel Drive (front: hubmotor 406, rear: my 250 Watt powered legs )
- Gear Ratio: 50t - 11t
- Date of Birth: November 2007

 

[Dee Jay]

some people just cant take a compliment

 

[fechter]

Nice job!

That's about as stealthy as it gets...
I don't even see the wires from the motor, how did you hide those?

Bet you can surprise the lycras when you pedal past them

 

[yapi]

Thanks Fechter,

The cables are hard to see but if you look closely you see the motor cable going up the fork on the "After operation Ebike (left)" picture.

Indeed other cyclists don't know what is happening to them when I cycle past them with twice the speed and only half of pedalling speed. The other day I was passing a police car when spotting them too late with 41 km/u. They must have thougth I was a very sporty bicyclist .

 

[Drunkskunk]

Nice Job!
I think I just lost my position as the stealthiest Ebike.
