New Member Glad I found this place

What's wrong with that bike in the picture ?
The phase wires are too long. Resistance heat, lower performance.
 
I think I mentioned I have been riding an Aipas A2 for a bit. I've got 266 miles on the ODO as of today.

Take what I was saying from the start as part not knowing part dreaming and part trying to be practical.

I'm learning the capabilities of electric and what's possible within reason and what fits within that reason for me.

I've got a new idea for a bike project in mind I'll mention in a second.

Neptroix to be honest you're bike looks good. A bike like that would probably work just fine for my needs.

That Warp, Wow that bike looks Bad AF! I honestly can only imagine what it would be like to ride. The acceleration has got to be dangerous! That bike is along the lines of my "Dreaming" I honestly could fab a frame like that without much trouble. Sourcing the mechanical components would be a breeze too. I would definitely need coaching on all the electronics though to build a bike like that.

I had decided to have a ready built gas fat tire bike ordered for me recently and didn't like it.

I may have mentioned building a 2 stroke with a Sick Bike Parts shift kit from the frame up years ago and it was sweet.

It accelerated like a rocket (for a gas bike) and could hit 40mph on flat.

But the pre made bike missed the mark for me.

Compared to the Aipas it was a crude experience.

To mention the roads I would often be riding most of them are not isolated bike lanes but very wide shoulder on Highway with 55mph speed limit.

I don't leave my bike at a Bus Station. It's taken with me on the Bus rack. I checked with the Bus Service and found that the rack has a max tire width capacity of 3" which the Aipas has.

On to my new idea for a build with refined expectations and maybe a little better understanding. What I was looking at was an off the shelf bike called a Massimo E14. It appears to be a Super 73 "clone". Same Suspension Fork it looks like. Full suspension. Newer model has a 750w geared hub motor (maybe a Bafang). At under 600.00 seems like it could be a pretty cool start.

The Massimo appears to have basically the same electrical as the Aipas I'm riding now with a frame that would offer a few interesting opportunities for modding. That and a little better out of the box riding feel perhaps.

The only downside I see would be I think the tires are 4" and it doesn't fold like the Aipas with those things perhaps being a non issue with what I want to do with it.

If the Massimo has 3-3.5" rims I should be able to run 3" street tires which would be what I'd want to do anyway.

Onto what I was thinking. A Massimo with a custom battery and maybe a Hybrid. The frame would allow a custom built battery that could be pretty huge. If I could add Ferro Fluid/cooling mods to the motor and an aftermarket controller to squeeze 35mph and get range out of it I'd be pretty happy with that.

The second more dreamer sort of idea (but I think definitely doable) would be replace the gas tank style battery with an actual gas tank and stick a motor into the frame. Then a White Industries Free Coast Crankset to a custom 4 speed rear cassette on the EHub or a regular rear bike hub or IGH like a Sturmey Archer 3 speed and a 500-750w front hub motor. If a Hybrid gas/electric a custom battery under the bench seat cushion.

What do y'all think?

I think such a build would be perfect for me. One it would allow me to spend a little at a time while having a functional ride most of the time during the build. It'd meet my requirements basically perfectly (having a gas engine for longer rides/legs of rides and an electric for cruising in the city/urban areas where a quiet and clean motor would be welcome)

It would start basic and cheap and then "scratch the itch" to do something a little different and complex with a possible outcome being an awesome and very capable custom machine.

What are you're thoughts? Pretty cool or no?

One thing I haven't mentioned. A piece of equipment that I think is ideal for charging that I own. I'm into R.C. models. My primary charger is an iCharger 206b it's capable of charging all battery types at up to 20a.

It's nice and compact and can run off of a wide input voltage.

Should work nice for fast charging a custom large pack right? I imagine way faster than the average 3a charger. I wouldn't want to damage my battery but I figured I'd build with quality cells and make it modular to be able to test and replace individual cells.
 
I can't follow you did you buy a bike already ,? Which one ,? How much you pay ?
A charger can only charge at the rate the BMS inside the battery won't allowed it. Usually two to three - five maybe 7 amps. Tops. How many amp charger came with the original battery. Most cheap batteries should be charged at 2 or 3 amp !
 
Hi yes I have two bikes right now. A gas bike I'm not thrilled with that I'm looking to return/refund (PhatMoto) and a Electric (Aipas A2) that I do like but it's basically on loan if I want to buy it I can and if I can afford (return works for the gas bike or I sell it) I can buy/build another bike and the Aipas will be kept by a guy I work for as an Ebike for him and maybe wife and/or friends.


I'm not proposing charging the Aipas at a high charge rate it came with a 3amp charger and because it may or may not be kept by me I wouldn't risk trying my other charger.

If I build/upgrade another bike like perhaps if I get the Massimo I mentioned I was wondering about fast charging.

What you're saying is if I was to upgrade/build a bike if I get a BMS that is capable of higher charge rate I could do 5-7amp.

Sorry I don't know what BMS stands for. I'll research that right now.

312 miles on the ODO today. 46 miles of riding today. I don't know if that's a lot compared to other people's rides but seems like quite a bit to me.

I think I could have done more distance comfortably on a regular bike but not at as fast an average speed though.

I think I did a 90-100 mile ride before on a pedal road bike that was probably 8 years ago when I was in a little better shape.

Maybe I should start a specific thread about riding the Aipas A2 and one for build ideas and general questions instead of in this introduction thread?
 
1.You can buy a gas bike ride it for a while and return it ?
2. What is O.D.O ?
3. Your boss bought you an electric bike you've been riding it for close to 400 MI and you want to give it back to him so he can give it maybe to somebody else ?
4. BMS in the old days we've called them battery murdering system. This was for used on a very high demanding people with big controllers and batteries and be a messes were more experimental. So most of us wouldn't run a BMS for our own bikes and just have sense wires like they do on our seat battery packs. I still have two balance chargers 9s through the balance wires up to 8 amps per channel. Plus I have four old higher end balance chargers in the broken box. Temperamental.
4. Yes it used to be the norm for a high power electric bike to run RC batteries and spaghetti them together four ass hard box 6s to make a 72 volt battery that's when battery fires are common. Can be very very dangerous.

First decide what type of bike you want what's it going to be for how far you want to go is it a pedal assist bike a throttle e-bike . How fast you want to go. etc
How much you have to spend ? Important this is so you can finish.

With the Gas Bike they're return policy is supposed to be 30 days. It's supposed to be returned in "sellable" condition which it would be. I rode it less than a mile. It had a defective part that I fixed with my 3D printer (throttle assembly) and a number of other issues. They should accept a return but I've learned since buying that I could have problems with them doing that.

O.D.O. (Odometer)

The miles I have rode the Aipas since new.

Going on 400 miles. Yeah the guy I work for suggested I get an Ebike to get to work. He offered to buy it and let me pay for it over time with my work hours.

I did a little research on the Aipas A2 and he ordered one. Then he ordered another one. I told him I thought it was a good bike. He's happy to have it if I want something else and that's why I ordered the gas bike initially was to have better range and to have a bike I could make a project too.

The Gas bike isn't as good as I thought it would be and I like the Aipas more overall.

If I don't get any contact from the gas bike company (reach a resolution on that easily) I'll probably be seeing if I can sell it locally.

I'll continue to ride the Aipas and either keep it (which is what I think I may do if I get the gas bike returned or sold)

Was entertaining a different bike which is what I mentioned before. I can only do that it looks like now if I can return/sell the gas bike because I'm to pay for it.

I'm probably not going to post here for a while because there's not much I'm going to be doing as far as an Ebike project goes it looks like for a bit.
 
Ok get your money back on the gas bike. You should buy it on eBay so you can return it or better yet with PayPal so you can return it.
Good luck with the electric folder that you have now just don't run it to empty only run it to 20% or 10% still left in the battery it's better for long battery survival and once a month leave it on the charger overnight allowing the BMS to do its job in balancing the battery if brought in too low or some other reason it would on balance sometimes it takes a couple days to rebalance the battery while it's on the charger.

For a fast electric bike it would be a 72 volt 3000 watt motor. IIs the battery that gets expensive.
But an old steel or crown Molly frame mountain bike are easily available for cheap to start with.
May I ask how old are you ?
There are automotive grade batteries that you can put together. But these you have to get lucky when they have the style of battery you need so knowing that ahead of time what better you need and you can buy it then buy the kit. I do have a suggestion for the kit.
 
Yeah if I can't get a refund on the gas bike I'm going to make it ride as nice as I can and then sell it probably.

Gas bikes can be really decent. I'm going to try and be more careful with who I buy from wether gas or electric or whatever in the future.

My age. I'm 39.

As far as what I'd like to build I'm homing in on that. What I think would be happy with for a first project is a Super 73 "clone" with a 750w Bafang hub motor (stock) and build my own batt of around 20ah. I imagine that I'd want a custom BMS and motor controller that's got a lot of flexibility for programming modes. Specifically the torque and speed for individual PAS levels and top speed.

Commercial bikes are limited to 28mph (The Aipas is) you know. I imagine with a 48v 750w Bafang a little more than 28 is possible right?

I don't want to push that setup much more but is 30-35 doable? I'd also like to have my pedal gearing cassette geared custom.

If I'm in the PAS 5 with Class 3 (28mph) on the Aipas gearing isn't quite high enough to keep pedal cadence reasonable. I'm pedaling like a madman if I can keep up with it at all.

The Aipas is 48v 11ah and if I get to 20ah on a modded bike (like a Super 73 clone) I think I would be really happy with that. Realistically after riding for a while 30-35mph feels pretty fun for me at least for a daily commute/city bike.

I'm not afraid to ride at 50mph and would also enjoy a bike that could do 50-60 but I'm trying to be practical and I don't need to be reaching for crazy performance in a first semi-custom build.

Should I be looking at 48 or 52 and can a 750 Bafang handle 52? Sorry for such a simple question. Suggestions for a cool controller/control screen and BMS (would like BMS and battery capable of fast charging)?

Is the Super 73 platform a good solution for a rider who likes to pedal? (that seat... o_O )

Anybody who buys one of those atrocities and thinks he will pedal is fooling himself. He's not fooling anybody else, though, about whether that's a bicycle.
 
So I was looking at the Massimo E14 as it seemed like it has about the same power system as the Aipas A2 I'm riding now but would allow a large custom battery to fit which the Aipas wouldn't. Also the suspension looks like it would be better than the A2 shallow travel front fork only suspension.

Yeah it's not exactly a bicycle (more of a large mini bike with pedals)

I realize that the seat height may not allow good leg extension to the pedals for best pedal ability. It didn't look to be super wide though.

I'm about 5'10" and was considering making a custom battery under the bench seat and thereby raising the seat a couple three inches which seems like it would help greatly with pedaling.

Yes I know 20" tires are kinda not the most fun to pedal but I've been pedaling a lot with the Aipas A2 and it doesn't bother me too much.

The idea wouldn't be to need to pedal much with a bigger battery and not concerned with it obviously being an ebike/Eminimoto with pedals.
 
I'd prefer my ebike to not need much pedaling. I have a regular pedal Cannondale MTB, legs and manual labor work for exercise.
 
Although maybe I should consider a mid drive for my Cannondale.

I don't want to damage it though. It's a lightweight aluminum hard tail. It's also on the smaller end of frame size for me which wouldn't necessarily be good at 30+mph.

The Aipas only has 3" wide tires though. This means q factor with the included 7 speed is likely a normal mtn bike q factor.

One a person goes 4" wide tires combined with 7 speed freewhel then q factor will be in the fat bike realm which means 200mm+.

Ahhh, ok. I thought you had said earlier that you were a dedicated pedaler. You can ignore my comments about the Super 73 platform not being conducive to pedaling.
 
I just researched Q-Factor and now understand what that is. The Massimo's Q factor seems reasonably low/average for a fat tire bike.

I would perhaps want to change to 3-3.5" wheels and tires if I got one and liked it.

The Massimo's seat height is said to be a little over 33"
I think that's pretty tall and would be about ideal for my size.

It could be reasonably comfortable to pedal.
 
I just researched Q-Factor and now understand what that is.
Yeah Q factor is a separate issue from the other problem you are mentioning which is the overall gear lowering effect of 20" diameter tires on the pedal drive train.

Fortunately there are numerous ways to fix this gear lowering effect of small diameter tires.
 
Honestly I think 20" works pretty good and there are a lot more choices of fat tires compared to 26" less expensive and higher quality options too.
