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 BikeBrand: VoilamartColor: BLACKWheel Size: 26 Inches recommendedFrame Material: Carbon SteelSuspension Type: Soft TailThis 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 MotorE-bike Battery 48V or larger (Weight of Assembled bike will recommend 48V minimum)3000W - 5000W Motor Controller (1500W works)Controller Display ModuleE-bike Throttle and Left Side Handlebar GripHeadlamp/HornHydraulic Brakes and Brake Disks - Front/Rear (Hydraulic is suggested due to weight of assembled bike)200mm Rear Shock Absorber and 12mm x 24mm BushingsHead Stem and Spacers (Straight)HandlebarsFront Shocks (Recommend Inverted Shocks with minimum of 130mm Travel)Decals for Buyers wanting CustomizationSpecial Tools Required: (Recommend Park Tools)Head Cup/Bottom Bracket Press (Used for Head Cups, not needed for Bottom Bracket on this kit)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. ### ⭐⭐⭐⭐ Good Value for Security and Durability, but Very Heavy. *by M***K on August 7, 2024* I got this frame a while back and recently completed the build, and overall, it's a solid choice. The enclosed casing is a standout feature, providing excellent security for the battery. It keeps the battery safe from potential theft, which is a huge plus, especially for high-powered e-bikes. The casing also makes wiring straightforward, with plenty of space to keep things organized and tidy.However, there’s one notable downside—the weight. This frame is quite heavy, which adds to the overall weight of the bike. While it's expected for a frame this sturdy, it’s something to consider if you’re looking for a lighter build. Despite this, the durability and security it offers make it a worthwhile investment for those prioritizing safety and protection, especially for the price! ### ⭐⭐⭐⭐⭐ Awesome easy to install and set up *by J***L on September 28, 2024* The media could not be loaded. Great finish comes with everything you need very happy with this set up.
