Is this budget friendly (ish) DIY eMTB possible ?

I’d cut the wheels from trampa. That’s a huge expense and you’re only getting hypa hubs. Go for These they are on sale right now and will save you a chunk of your budget

Or just tell him trampa is our of his price range and start w an mbs pro complete like someone posted above

Sorry mate but £50 MBS rockstar + £50 tyres from Ali is going to win every time if you want best bang for your buck

Plus TB wheels are kinda sus

I agree. I just was showing a cheeper option. What Ali tires do you recommend? I’m always searching for new tires @moon

@Venom121212 @Pedrodemio Might know.

Also those hubs are only for 8/10mm axles

IMO, budget emtb is 100% possible and anyone saying “DIY is always more expensive than prebuilt” is just not telling the truth. Its only the case under like $600, and even then what you get for a prebuilt still has disadvantages not measurable in specs. You can do some really heavy offroading for about $1000 or so.

L-Faster matrix I clone trucks and mounts with flipsky 6374 140kv motors ($300)
Unity with active fan cooling if possible ($225)
12S LiPos ($200)
Pelican case ($30)
Silicone sealant, wires, connectors and shit ($50)
Mini or GT2B/RC remote ($13)
MTB Deck of your choice maybe a comp 95 ($100)
Bindings, extras etc $100

Total is like 1k$. It will do actual serious offroading (If you’re not especially heavy)
Example rides using a similar build costing about 1k

Its simply not true that you “need” a 63100 dual VESC6 gear driven trampa $3000 build to offroad. Its nicer on it, buts its not “impossible on a budget”

I just received this one yesterday, but I have no idea if they are the soft or hard version that lasts forever

@Venom121212 could you tell if I took some pictures?

Yeah, the shinier they are, the harder they are usually. The more matte, the more likely they are to wear down imo

What would you say? Middle one is Ali, right is Trampa and left wheel chair tire I bought around here that wore down half in less than 100 km

That one looks good to me visually.

I’d take the tubes out of it and the known soft one of similar size and squeeze them both laterally and towards the center of the wheel to see if it is a noticeable difference in firmness. Hopefully there should be.

I think I have you beat on price.

$232 Ali Trucks+Motor Mount+Pulleys+wheels+belts
(I’ve personally used this HW and it’s actually really solid. Took a bunch of abuse without moving at all.)

$100 Deck from MBS (there’s many options out there for this price, I suggest used.)

$170 Maker X Motors

A 12s5p can be built for roughly $250 if you use these cells and this BMS ($15)

I’d charge $550 to build it for someone local


ROUTE 1

$50 Remote

$40 Anti-spark

$22 BT Module

$150 VESC


ROUTE 2

$295 UBOX VESC+BT+Remote

$5 Loopkey Anti-spark


$10 Box


TOTAL: $1100 ish
+$75 for a fast charger

This is what I quoted my friend who wants to upgrade from her zealot and keep up with all the $2k+ boards on the group rides. This is assuming I provide my labor for free and she re-use her 12s charger.

Edit: I’d charge $550 to build this battery.

That deck is tipped at only 20° IIRC.

Makes for a terrible turning radius when coupled with zero degree mtb trucks.

Deck swap and that is a decent list though for a beginner board. The less flipsky the better though.

Given my experience with that esc so far, it would probably overheat in off-road conditions if it’s closed up

You’re right, ideally, you’d get one used for a better value. Also the drivetrain comes with angled risers if it comes to that.

All about the value, hard to find better stuff for cheaper.

The use-case im thinking is group rides with grass being the most off-road it’ll see. Also a heatsink can easily be improvised

At that point I think the uBox might be a better value. It can replace the antispark, remote, and BT module since they’re all included, but you also get a 75V/300A system with integrated BMS support, and horn/light outputs. And it’s like $10 more than all the separate parts combined together, and cheaper during sales, and you save on shipping since it’s only from one place.

Very true. I will update it.

It has a heatsink, a pretty decent one, but even on a cool day, mine is hitting 75 degrees easily an thermal throttling (specifically with those motors @80 amps each), closed up in my enclosure

You guys have it figured out. A few more budget friendly suggestions though…

Two 6s lipos w/ the highest mah you can afford or <$150/batt in a pelican case. Easily accessible for easy out of board charging, or wire up a charge circuit and a bms, idgaf.

The ubox is a good suggestion, and best buy for the money since you get so many extras included, however, I still think a dv4 + some cheap, battle hardened 6355s + a high ratio would produce a very capable mtb and save you some $$$. Remember, ppl like duffman are running 6355s and those little v4.xx singles.

20 degree tipped decks are overcome by the giant angled risers that come with most of the matrix I clone trucks, which are also the best option for budget builds. Added benefit, you can run thane on those 10mm axles :wink: Get the upgraded motor mount w/ the cage, it’s cheap and sturdy.

Really, an entire L-faster kit minus electronics is a good starting point for a budget mtb build.

Could /should make a whole and epoxy the esc on it airflow 1000

I believe the antispark option has been taken out tho. Should still make a key switch with an xt90
