DIY 35MPH Trek Electric Bike Conversion | 1000W E-Bike Kit

After installing the Voilimart 1000W Rear Wheel DIY e-bike Kit from eBay on my old trek mountain bike, i review the overall kit and the process of installing all of the components. I also show the performance of the kit, with overall uphill speed exceeding expectations and top speed hitting almost 35 mph.

I got the 1500w kit with internal controller and I have over 4000miles on it without ANY problem whatsoever!!! I highly recommend this kit. I can go 39.9mph and I get a range of about 40-60 miles out of a charge with my 54v battery..

[@maxpower001]

All water proof connectors, plug and play EVERYTHING, I built the whole thing in about an hour and a half and it's one of the best vehicles Ive ever owned.. Doesn't make a sound and is way faster then the average 50cc scooters that "try" to race me.. and a few go- karts as well

[@Debbiebabe69]

These kits ('Voilamart' are simply drop shippers who put their own name on the kit, many sellers sell exactly the same gear under different names) are quite simple to install, helps if you have a bit of experience repairing bikes but no engineering background is needed, and for most of the kit, the only tools you need are a set of allen keys, screwdrivers, pliers, possibly mole grips/wrench if the back wheel nut is rusted on, and a small socket for the protective junction box (you can pick these up at poundland or supermarkets). There are only 2 problems that occur during installation - the first is the pedal assist sensor, that requires you to take the crank (the bit of metal that connects the pedal to the bike) off, which often requires a large automotive-grade socket set, which is extremely expensive professional-grade gear. The second is the connection between the battery and the kit. As you are buying the battery separate from the kit, and there are many different types of battery kit (heilong, silverfish, generic heatshrinked 18650s), it usually happens that the kit and battery have completely different connectors, which means you have to snip them off and put the connectors you want on - meaning either soldering or crimping.

[@Jo060]

A crank puller can be had for less than $20.

[@Debbiebabe69]

@@Jo060 yes the crank puller itself is cheap, but there is often a nut that you need to take off to get to the crank, and because it is encased in the crank housing you cannot just use pliers.

[@groundskeeper5292]

Saw you got it up to 32 there for a bit! Pretty fast for a bicycle. Nice build. I have the same one on the way for my old Trek. Thanks for the info.

[@kenbad8271]

Your kit is actually approximately $278.00 I don't know if that's what you paid at the time you bought it but that's what it is now which is a great price for everything you get when I was buying the kits when they first came out Violamart, was selling them for a little under $300 and you didn't get the LCD so this is a great price and I will be purchasing this kit very soon.

[@zeebries1271]

Never expected to find a voilamart kit with the exact same bike as mine so a few tips picked up there thanks!

Torque arms are often overlooked, I installed one on my bike even though it is a steel frame and not aluminium.

[@travis938]

ALSO INSTALLED WRONG 50% TIME the torque for 1000w is extremely little less than 500w geared hub... avoid front motor is best advice . good torque arms need proper installed than helps

[@michaelkertes3852]

oh darn, I don't think I'll be able to do this as I don't have an engineering background. Can you help me @TechRoundUp?

[@RickDean]

Nice video. I'm considering the front version instead of the rear. Any comments on why I shouldn't would be appreciated. Rick

[@TechRoundUp]

Rear gives you bit more power, but the front can be a little more risky when it comes to handling and braking

[@evananthonybaez]

Front i dont think has paddle assistance

[@FlyingFun.]

Front forks are weaker and may break esp if aluminium. Front wheel is prone to spinning and could cause a fall. Steering will feel a bit odd maybe with the weight. Back wheel isnt too hard to do, I did mine no problem with very basic tools and knowledge.

[@Briany0u2006]

been wanting to do this for a long long time, but dont have the money.

[@aitathakali2457]

Brian y0u what is the total cost ?

[@E-BikingAdventures]

The pedel assist sensor does not tell the controller how fast you are pedeling and then in turn, determine how much power to send to the motor. Its there only to sense movement. The PAS setting you have it set at determines how much power is sent to the motor while the PAS is sensing movement.

[@electricchoppers]

Great video 😎 Ebike kits are so simple now!

[@grantvogel5209]

2 things to say, I have the same kit and I have not yet added the pedal assist feature because I didn’t have the tool, and I also use a different 15ah battery from eBay, and I consistently get like 30 mph and at least 20 miles range

Would like to convert my trek 3900. Yours looks exactly the same as mine. I realize there are differences. Mine also has integrated brake and shifter...prolly same one. I applaud your ingenuity. I would kind of like a more integrated or separate solution for the brakes. Your video brought this to my attention that I would need to figure this out. I guess I would need to buy separate shifters to match gear configuration front and back separate from brakes? Anyway. I am still looking around. thanks.

I had the same problem I just cut off the levers of the brakes then installed the ones that came with the kit and pushed them up against the shifters if done right nobody can tell a difference

I've just purchased this Kit and it's still in It's box, waiting for the battery, I'm very new and very Inexperienced In fixing up bikes but I'm going to have a go at it, I have a road/hybrid bike to fit the kit to. However my brakes are Cantilever and I see that this Kit has 2 Brake connectors from the Controller, I've read that when the brakes are applied that it will cut out the motor.. can I use my existing brakes for this or do I need to upgrade my brakes to Disc Brakes? Can you help and advise? Many Thanks, Jeff

[@icebiker3]

The instructions that come with this kit are bloody awful. I bought a front wheel drive to go on my home built trike. It was a real experience to build character. I am a retired engineer mechanic, and this was a challenge because I did not expect the torque produced. The instructions do not tell you how to mount the special washers, and I had the wheel tear out of the fork twice, tearing up the cables before I figured it out. I then changed to a heavy duty fork and ground the fork to fit the axel and washers, then I made a retaining torque arm to prevent the motor from going a different direction than the rest of the bike. You have to be careful. It produces a lot of power, but is kind of poopy on steep hills. Still and all, this is a great thing to try, and cheaper than a new electric, although you can now buy a new electric bike for USD1750.

[@icebiker3]

@will kinh The plain washer goes on first, then the frame/fork, then the washer with the tab on the outside. The tab is critical, and is supposed to be, I guess, a substitute for a torque arm. The tab needs to be set into the axle slot, up against the lawyer tabs so it is trapped in there. The frame might have to be filed out to fit everything; just be careful to not make the slot too wide. I would also suggest a torque arm if you can get one.

[@sanesaint8725]

I got a back bike rack and put everything in there doesn't even look like a need like except for the hub cop looked right at me just kept driving

[@sanesaint8725]

You don't need to do the pedal assist that's just if you want your battery to last longer batteries last up to 3 years maybe only two if you don't use your pedals but what's the idea of an e-bike so you don't have to pedal

[@small-timegarden]

@Tech Round Up hi. One of the difficulties for me...not so much now...but I'm still learning... Is how to match the battery to the DIY kit. Since they come as separate items I am thinking that you have to have some sort of understanding of current and voltage In order to appropriately match the battery with the DIY kit. I don't know if I missed it in the video but what Are the specs on the battery that you purchased please? I actually went to the link that you have in the description but it is nowhere to be found. Thanks

[@TechRoundUp]

It of course depends on the motor kit you buy and how long you want the battery to be able to last, but I went with a 48v 13Ah battery. As long as the voltage matches the motor and the battery says it supports the wattage, it will have enough amperage to support

[@driftathug]

Are you able to remove the battery to charge?

The battery is separate from the kit. If you buy a Heilong style battery (which is what this video shows) then yes, the battery is removable, and the carrier and wire stays on the bike.
