Love the kit"¦came rather quick, I was able to use a 27.5 inch wheel' I had so much room I could got with fat tires, if I wanted' I mounted a 28.5 inch rim for research, and it fits that size to"¦.so this kit can fit wheels all the way to a 28.5 inch rim.

The only complaint would be not being able to fit the speed controller in the bottom holder, but it's no big deal"¦most 3000watt and up speed controllers won't fit"¦depending on battery size"¦you can fit it on the inside of frame, and it came with no instructions, you can use YouTube if you need info"¦but anyone with common sense can put it together.

It wasn't too heavy"¦I was able to carry the box over my head, or maybe I'm strong Lol.
The kit came with every bolt needed, and a key ignition"¦Love doing DYI because you can do any custom design"¦.to make it look Unique.
Will update my pictures once I get it completely assembled.

Wow, is all I can say. This kit is really nice and stable, is also available at an extremely expedient shipping speed. Most kits on other websites take months to get. Not this one. Voilamart has some in stock in American Warehouses. That is a huge plus for me, so much so, I am going to help them sell this better and below I have written a description of what they should have written for a kit description, but assume they did not because of the communication gap in languages.

I have also provided a list of parts you need to complete an entire bike assembly and recommended special tools.

With the proper front shocks, this bike can be a really nice Fat Tire Bike for 26inch x 4inch tires. Rear dropout seems to vary in width between 170mm - 175mm which is plenty to have a Fat Tire Bike wheel mounted on the back. You will need front forks to accommodate a Fat Tire if a Snow Bike/Fat Tire Bike is what you are wanting to build. I highly recommend this kit whatever your build will be and the price is extremely competitive at $381 including taxes & shipping for Amazon Prime Members.

Bike Type: Electric Bike
Brand: Voilamart
Color: BLACK
Wheel Size: 26 Inches recommended
Frame Material: Carbon Steel
Suspension Type: Soft Tail

This is a carbon steel Bicycle Frame Kit for a 3000W - 5000W Electric Mountain Bike Build. Suitable for most wheel sizes：27.5/26/24/20/18 inch
( I am using a motor rated at 48V/1500W/38-40mph. Battery must match that with E-Bike Motors )

Durability Material: Carbon Steel (thickness 2mm), Steel side covers which are high quality industrial, and glossy.
Net weight of the whole kit: 23 KG/51 LBS.

( Careful inspection of the welds, the automated welding done on this kit is above and beyond phenomenal. Very good quality )

Kit will include the Frame Body, Saddle/Seat Bracket, Underside Controller Cover, Rear Flat Fork/Dropout (including Sealed Tapered Bottom Bracket Assembly)，Removable Battery Casing/Tray, Head Tube Assembly with Cups, Cover Panels, Bolts/Washers and Ignition Switch for assembling.

This style of frame is first choice for assembling an Electric Bicycle DIY Kit: Anti-rust treatment inside and outside the steel tubes, provides longer service life. Spray VHT Rust Convertor on insides of tubes for extra protection.

Robotic welding, more stable in quality.

Rear Shock Requirements: Bushing width 12mm x 24mm, 200mm shock eyelet spacing for ordering a suitable Rear Suspension Shock.
(You will need some sort of studs, washers, and nuts or pins to mount the shock. Make sure the shock comes with Bushings. Typicaly you will need 8mm x 40mm or longer studs/bolts/pins)

Battery Cover/Tray will hold a battery 13-1/2" Length x 4-3/4" Wide x 7-1/8" Height
( 342.9mm x 120.65mm x 180.975mm )

Rear Sway Bar Bushing with this kit is metal and not a rubber bushing like other kits.

Items needed to complete a fully assembled bike.

48V - 72V/3000W - 5000W Electric Motor
E-bike Battery 48V or larger (Weight of Assembled bike will recommend 48V minimum)
3000W - 5000W Motor Controller (1500W works)
Controller Display Module
E-bike Throttle and Left Side Handlebar Grip
Headlamp/Horn
Hydraulic Brakes and Brake Disks - Front/Rear (Hydraulic is suggested due to weight of assembled bike)

Special Socket Tool/Wrench for Bottom Bracket removal when it is time to service the cranks and grease bottom bracket which should be once per year or more, depending on riding style.

NOTE: Depending on motor, some motors may require special mounting hardware to sit properly on rear dropout. Most notable is motors that do not have a way of keeping the motor from spinning in the dropout slots provided, that applies to any DIY E-bike Motor Kit. E-bike motors do not operate like normal bicycle tires. E-bike motors have a lot of torque applied to them and in most cases need extra mounting hardware to keep the motor axle from spinning with the rim and binding/winding up your motor's power wire around the wheel causing catastrophic harm and or expense. This is not the fault of the dropout, but rather responsibility of the motor manufacturer. Under no circumstance should you rely on the flat parts of the axle to keep an E-bike motor in place from spinning. The axle is what the nuts screw onto to tighten the wheel to the frame/rear dropout.

I had to custom cut the bolts where a "controller" would mount and cut a hole in the side for my charger to mount. The rear swing arm is heavy as hell! I use this thing for street use only and probably will never take it off road because of how heavy everything is. It comes with a battery box but did not fit my battery unfortunately. Had to use quite a bit of spacers for my brake caliper to seat properly on the disc brake. I was pleasantly surprised that this is now shipping with a key switch has two plugs and that controls my lights and my battery which adds to a bit of security. I am not too fond of how small the screws are for the bottom cover and side covers. Over all, solid frame. I went from the old plastic cover frame to this one which added about 30lbs to the bike overall.

So far it looks good, very heavy duty like a tank, will not break easily. I am attatching a 8k watt rear hub motor to this frame and a 72v 40ah battery pack. Just waiting for the parts purchased from Amazon. If I knew how much I'd spend, I would have just bought a Telaria 3X for $3k because I spend over $5k already and still need more parts. So frustrating but not many people have this look so that's also nice, and I got the motorcycle seat so it looks really cool too! I will update with a picture after I put it together fully.
