Voilamart Electric Bike Frame Steel for 48V 3000W-5000W Stealth Bomber Electric Bicycle DIY Kit E Bike Conversion kit-White/Black

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 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.

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 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!

The media could not be loaded. Great finish comes with everything you need very happy with this set up. Fits 2 72v 20ah batteries very sturdy and pretty universal conversion from a 26” MTB

It’s not too bad for the price… I bought the B3 kit. I do have some confusion as to where the push start and alarm are supposed to go…. The frame came with no assembly instructions at all… I do know how to put these together for the most part but there are no locations for the push start or alarm unless I modify the frame myself which I would like to avoid. I contacted customer support and it’s been a week and still haven’t heard from them… the frame is pretty narrow but my battery does fit ( it’s really tight) I’m still waiting on the hub motor kit I ordered… went with 20” fat tires for a lower ride and so far it looks nice… you cannot use a motocross style seat either which was a downfall because of how the frame and seat mount were built… I wouldn’t get the other versions because you can do it all separately for half the price…. I may send this back for a refund and go a different route…

came with most of the things you will need including headset bearings took new paint well

Facil de armar muy económico y muy resistente

Barley any welds on the rear swingarms ruins the entire package definitely wasted money as I'm gonna have to replace it or do my own welds I paid for a fully built frame not scrap metal mock up of a swingarm

The frame ok :(Cheaply made. Some of the welds are barely tacked down and the thickness of the steel varies. Like the base next to the rear shock absorbers is like an inch thicc but the entire side's are tiny- it really gives a flimsy feel. The paint is fine, but the description indicated that the metal was treated to prevent rust- there is already rust in the post for my forks!! (Like factory oem rust) The threading for the screws is already questionable- literally the finest threads were used (probably because the metal is really thin on the side panels).I also order 2 wheels from them; not worth it, but the frame is …. Oook ig
