Your Creation's Before & After Pics

2x ebikeling 500w front hub conversions in 79'er (27.5 in the back, 29 up front).

Hers is an off the shelf Cannondale Tango 4, with a Surly ECR Fork. Brake upgrades coming, though the MT200 hydraulic disc brakes have surpassed expectations, so might just leave it.

His is a frankenbike. Marin Muirwoods frame, 10 sp Deore clutched deraileur, microshift bar end shifter, and hylex brakes.
Getting a small size outpost frame bag (medium wouldn't fit anymore after adding the battery), and will move controller into that. For now, it sits in my toolbag.

Both have EM3EV 52v 13.6Ah batteries. Hers is held on with a strip of 2" adhesive velctro (using 4 leather screw posts to hold to battery base) and 1" webbing/buckles.
His is held on with a power grips fat strap, and bottle cage mounts.

My Azub Six SWB ‘bent commuter ride gets treated to an upgrade
I came across this bike on Ebay a few years back. I had wanted to try a 'bent for years and this one was barely used- seller was asking basically double the price of the Rohloff alone for the whole bike ....ummm....SOLD!
So since that heady day I've had a couple attempts since to electrify- I ran a bafang middrive for a time but I didn't like how it was loading the Rohlhoff. I think this here is the best version

I laced a 24v MXUS XF07 up front driven by the Grin Baserunner paired with a V2 Cycle Analyst. Rim brakes changed Avid BB7 Mechanical disc brakes front and rear.

The battery is a home built 14s6p using 4-cell holders wired together. I charge to about 57 volts, a little lower than a ceiling charge for pack longevity this gives capacity for 50+ miles (maybe much more at ambling comuter speeds.) I don't run a bms and so I have a connector for keeping an eye on battery balance. Only very rarely requires a slight balance. Paired with the Grin Baserunner, I am pleasantly very impressed with this little controller. Till now I have only experience with Infineon type trapezoid controllers. I am in Europe and so the Baserunner, little brother of the Phaserunner, is just perfect for a commuter build. Although it doesn't make the geared motor run silent, as I thought it might, it did eat up our town’s longest, steepest hill, which it took at moderate speed (16mph) without even breaking a sweat :thumb: Tuning the Baserunner to the motor was straightforward and painless. I’m well pleased Highly recommended - thank you Grin for an amazing product

Last job on my ride is to hide those wires as well as water-proof the battery, which I usually do with a black fabric wrap coated in fabsil.

Best, Paul in UK

Before:



After:



2019 Gravity Bullseye Monster FIVE with a few upgrades. I blew the motor after shunt modding an e bikeling controller.

Kit is a voilamart fat 1000w kit, running at 3.7kw under full tilt. Current rewind on motor is 13x4 24ga temco 200c wire terminated WYE.

Battery is 4x xiaomi m365 packs broken into a 13s 9p pack with a shunt modded amazon bms.

86A at 48v or so full throttle full charge. 38.6 MPH is the highest top speed ive seen.

Build thread will popup at some point.

Here is my Cyclone 3000 using the GNG brackets. no before pic but it is a "parts bike" with 26" downhill rims and Shimano parts.

Frame: Brand X HT-01 (73 mm bottom bracket with the GNG bracket bolted to the ISCG mount)
Battery: 14S5P Samsung INR18650-25S in a Reention case, stock Cyclone controller modified to 55A.
Motor: Cyclone 3000 stock with GNG brackets and freewheel etc.

Tried to keep cabling and cable ties to a minimum so it can pass as a factory ebike.

Initial impression: it's like driving a diesel- serious torque off the line, but low RPM. it can wheelie and if you row through the gears has some gnarly speed, but I am wondering if 72V would have been a better choice!

I've been on this forum for a couple of years now and have built four ebikes. Yours is one of the most appealing I've seen on here. Love the understated look/colors but with the bad-ass motor snugly mounted and prominently displayed. Super cool dude.

Thanks! I commute every day on this so want something reliable and rugged, that didn't look like a science project gone wrong. Also I hate cable ties and insulation tape.

My new Monster bike. 21 LIPO bricks in config 3Sx7P which gives nominal 72V 35Ah on an old skunky GIANT frame. Sabvoton controller and 3000W capable hub motor. All enclosed in 3d printed plastic case waterproof and snapping toghether . The bike handles very well as weight distribution is mainly in the center of gravity. Replaced the cheap and weak v-brakes with some old but very strong magura hydraulic pads.
Bike is very powerful. On the flat I recorded a speed shy of 80 km/h. At more moderate speeds like 30-35 km/h I can easily reach 200 km autonomy with very little power contribution of my legs.
Hope you enjoy the pics

IT...


So... about a year ago I bought my mate's old work bike for £15 to ride down to the boat.

Fail... Too much work with a pile of stuff to carry (water, food, rum... the odd outboard engine...).
So the frame ended up locked up outside in the rain. Time passed.

One morning last month, on the way out to buy "essential supplies", I find a group of teenagers calmly dismantling "IT". Apparently they need an inner tube. Ha! Gave them an earful and dragged my poor mangled bike indoors.

And remembered seeing something about converting bikes to electric...

Wilko
£5.50 Clear lacquer
https://www.wilko.com/en-uk/wilko-clear-lacquer-spray-400ml/p/0413850

The frame was stripped of paint, washed in acetone then sprayed with lacquer and has not yet started to rust despite exposed places she has been locked up.

The battery is 2x 8s6p of mixed 18650 cells in series delivering 62v at 70% charge. 10 year old cells.
I tried to keep cells of similar capacity in each row, which were taped together with pvc tape (also serves to provide an air gap between rows). Cells are soldered together with 240v 5a mains cable (copper) wire, and stuffed into 2L milk containers cut to leave the handle which is folded over and taped... Handy.

It is a horrible bodge - the solder regularly parts from cells rendering rows out of circuit. I cut the battery open, add more solder and reseal... leaving the layer of pvc tape and adding more. Foam pads are taped to the sides. The extra padding is slowly decreasing these service jobs!

The batteries are "secured" to the frame with the external black pvc shield I stripped off the bus bar wires, and covered with a piece of cloth from the back of an old shirt (it looks too much like a rolling bomb with all the black tape and cell readouts so had to be covered!).

Currently manages about 5 miles of no effort cycling (just short of a return to the boat need more cells!)

The controller is in 250w mode.

Hope you like the pictures sorry they are terrible!

First revision was with a BBSHD. We have built the battery compartment ourselfes. 14S6P with a 30A BMS.
Ground clearance was awful so I had to switch to a X1.

Donor bike's a 2012 Mongoose Fireball from Gumtree.


V1 build was the cheapest full kit I could get in Australia ($536 including 10Ah battery).



Success of that meant a full makeover with BBS02b, Em3ev 48v Supershark. 42.8Kmh throttle only. Yum!

Filth, that battery box is proper nice. I need one. Here is mine, no before.

Just finished installing the cyclone 3000 from sickbikeparts.com into my northrock xc00 fatbike, battery is a 72v 24.5ah with lg mj1 cells from litespeedbikes.
Now i know what torque feels like lol

The fork is a 26", tire is 24", so thats 2" extra there..

Whoops, nope you only gain 1" clearance there on the radius, not the 2" on the diameter, 1" above the axle and 1" below the axle.

Yup it rubs. Not a game-ender tho. I still have alot of fun on it. Can jump and line lock and pretty much all around abuse it to well beyond other capabilities of the bike.

But year .. it rubs , now after riding almost a year and a 1500 mile+... I see the evidence. I could make the box a little thinner but I wanted to accommodate a 24s pack in that box. It is a great fun bike on the street and light trails. I got prolly 1500 miles on it.

I was just trying to play it up like "Yeah No Problemo, this. " Lol.

I bought this bike because it met the following requirements.

• Available at a local bike shop
• Pedal forward design for more upright posture
• Disc brakes
• Fat tires
• Lightweight Aluminum frame
• Large frame size and wheel base
• Well documented builds as both BBSHD and Leaf hubs.

Here's my Electra Lux 7d Fat Tire I purchase brand new in December 2019. I started saving for a as yet unknown conversion kit as soon as I bought this bike.


When I realized I was getting a stimulus check I finalized my kit choice and choose EM3ev as my vendor:

• MOTOR: BBSHD Kit
• BATTERY: 52v 20ah Triangle Battery

Going with a vendor from china was a little sketchy during the pandemic but I was in no hurry and it was the only compete kit I could afford from one vendor. As this was my first build I wanted a complete kit from one vendor.

The motor and accessories arrived in about a month but the battery took a couple of months. EM3ev provided me with the ability to track my shipment so I just had to be patient.

The build went well and I had no issues with my kit. I will start a build thread later.

Meet "Miss Mino'aka" (Hawaiian for smile). I love the stealthy look of her with the motor in the frame.


Here's a better view of the motor mounted in the frame.


I can't make up my mind about the basket. I'm not sure if I like the look and I was planning on mounting a huge headlight there. My second accessory was the racks and I have panniers coming so I'll have cargo options.

I never rode an e-bike until I built this and I'm blown away. I assumed I would mostly use the throttle but I actually like the control I get using pas. I use the throttle mostly for burst of speed when I need it or help getting through an intersection as quickly as possible.

If this had been a standard mountain bike with a diamond frame the build would of been simpler. With the help of builders sharing their build experiences via forums and youtube my build was relatively easy and trouble free. I now have exactly what I wanted with the satisfaction that I built it myself and the feeling of security knowing I that I have the skills to fix/upgrade whatever comes in the future.

Great work! I need to try a pedal forward bike sometime.

Thanks! It's very comfortable and relaxed. I really like being able to put my feet flat on the ground at stop lights while I'm seated.

Very nice. I bet that can climb anything.

Fitted a 70T change ring. Now I can at least half pedal at speed.

Hi im new here,
thats my build.

QS 205 5T with reglued and painted magnets, Statorade and Hubsinks
Sabvoton 72V 150A
3,5kWh battery 20S 14P Samsung 35E
Rockshox Boxxer
Maxxis 70/100 Maxcross

This is one of my videos how i ride
https://youtu.be/ivjZmJguGys

There are some older pics, i broke a lot and upgraded a lot. New excell rim, spokes, stator, fibreglass sidepanels, rockshox, ...
The first one shows how i fit everything in. I spotwelded the battery myself with a Sunkko welder.

before:


After:
cyclone 3000w, phaserunner, 72v homemade battery and case, home made motor mount. 55 mph top speed.

No before pics because it was built up from parts. Total bike weight as you see here is 36 pounds. Goal was to build an e-bike I could ride long distances even without power assist.

Aluminum track frame from bikeisland.com. Kit is Ebikeling 500w 36v hub motor. Battery is homebuilt - 10s4P Samsung 35E cells (total of 14ah) Cells are placed into a "downspout case" utilizing 3d printed endcaps and bottle mount. Various parts I either had or purchased off of ebay.

No front derailleur, just 46T ring gear (Vuelta crankset). However there is a wide range 11-34T rear 7 speed cassette. Gear coverage is good. I can climb hills and do well on the flats. Special adapter is used to attach derailleur to track frame drop out.

3d printed parts abound, special mount made for ebikeling computer to mount on stem. Various cable clamps.

I use an integrated Shimano 7 speed click lever shifter/brake on the right side of the bars and the ebikeling brake on the left side of the bars. Only the left front brake switch is connected to the controller.

I disconnected pedal assist sensor because I only use the thumb throttle when I need a boost. Otherwise I'm typically pedaling.

Caveats:
I think I am going to re-do the battery mount to make it simpler, stronger, and more universal. I will post the 3d files on thingivers.com when I get it done.

Rear wheel is heavy. I would like to buy a set of carbon rims and relace both wheels. On the rear I am considering a "36 hole hub laced to a 24 hole rim" as discussed on Sheldonbrown.com Too much rotational inertia on the rear wheel.

I still have a large amount of excess wire harness stowed in the bag. Need to take the time to cut/re-splice the cabling.

The track frame is 120mm opening. Fitting the hub motor is difficult. But I can manage. I am afraid to attempt to spread the stays because the frame is aluminum.

Nice clean build, it would be perfect is you hide the red on that wire with a cover.

Have been thinking of a low power long distance bike. Good job.
If your controller is in the bag, would find a way to get it out in to the air.
