Giant Suede Replacement Battery

I’m looking to get back into ebiking after a 3 year brake. I’m looking for a good starter bike that I may be able to amp up a bit. So I found a Giant Suede E for a good price locally but with no battery. It’s even missing the case.

How hard would it be to rewire with a new battery either shoved into the central fork slot or even put on the rear rack?

It shouldn’t be too hard if you know your way around a soldering iron and a tool kit. The original battery should have been a 36v 9Ah NiMh. Those aren’t used anymore, as LiFePO4 is a superior technology. Pingbattery.com would be a good place to get a reliable pack. A 10Ah pack would work with your little 350watt motor, though a higher amp hour pack will give you more range.

Good idea, but a Ping 10Ah will not fit in that slot.

I customized a Giant Suede E for my wife and modified the casing to accept lipos, so I’m very familiar with the frame. If you cut out the fascia, you’ll have room for a bigger battery, but a Ping is still a stretch as there is only about 150mm of space from seat tube to wheel.

You can use any battery mounted wherever you want however you can. A rack battery would be very easy. I like these ones because they bolt to your existing rack: http://www.bmsbattery.com/36v/162-36v-10ah-lithium-ion-alloy-shell-ebike-battery-pack.html

You can gut your old battery, and use case as a toolbox or whatever.

Here’s a bike that I did that to. The original case now houses a much bigger than original controller at the bottom and my waterproofs above it.

Although you CAN mount the battery anywhere, I would suggest keeping it between the wheels. The bike has a good natural handling balance due to the pack being directly under arse. The men’s version of the Suede E has a decent triangle, so I would put it there if moving out of the premade area.

I just had my first ride with my 24S bike and fork mounted batteries. And while it was stable at speed, low-speed maneuvering suffered more than I can accept. All my batteries will be frame mounted from now on.

E-Bike Batteries Are Causing Fires: Is Your E-Bike Safe?

Repeated fires have prompted the FDNY to release recommendations for the care and keeping of e-bike and other lithium-ion batteries.

  • A spate of fires caused by lithium-ion batteries throughout New York City on April 21 has prompted the FDNY to issue lithium-ion battery safety tips, including for e-bike batteries.
  • Similarly, a Florida bike shop burned down on April 9, after a refurbished e-bike battery was left on the charger overnight.
  • E-bike batteries can be fire hazards when used and stored incorrectly. Below, we discuss how to use an e-bike battery correctly.

Between New York City’s fire department (FDNY) issuing a warning about e-bike batteries and a Florida bike shop going up in flames after a battery was left unattended on a charger overnight, it’s been a worrisome week for e-bike owners. But don’t panic: Your e-bike is likely safe, but consider this a warning to check your e-bike battery charging and storage practices.

Because lithium ion batteries—commonly found in everything from cell phones and laptops, to e-bikes, scooters, and electric cars—can store a large amount of energy, improper care and keeping of the batteries can result in fires.

“If using a lithium-ion battery, follow the manufacturer’s instructions for charging and storage. Always use the manufacturer’s cord and power adapter made specifically for the device. If a battery overheats, discontinue use immediately,” the FDNY tweeted earlier this week.

From Bicycling

New York Daily News reports that the FDNY was called to the scene of four different fires caused by lithium-ion batteries, all on April 21. The batteries were used in an array of vehicles ranging between electric motorbikes and scooters. The vehicles pictured in the fire department’s tweets are all motorbikes, rather than e-bikes—but e-bike batteries have caused fires in the past.

The largest of the four fires reportedly happened due to several batteries stored on a work shelf. While no deaths were reported, 12 people were injured in the fires. And the FDNY issued the grim reminder that four people were killed last year in fires caused by these batteries.

How do you prevent charging incidents like this from happening to your e-bike? Avoid aftermarket and off-brand or bargain batteries for your bike, first of all. Stick to the manufacturer’s specifications and recommendations. Furthermore, e-bike batteries that are charging should never be left unattended. If you’re charging your e-bike in the garage, set a timer to remind yourself to unplug it when it’s done, and if you’re leaving the house, unplug it and finish charging it when you return.

Bike shop owners should be just as careful. Unfortunately, earlier this month, Andante Bike Shop in Cutler Bay, Florida, learned this the hard way. The shop was destroyed on April 9 when a rebuilt battery was left on a charger overnight. While a normal e-bike battery from a reputable brand shouldn’t set itself ablaze when left too long on the charger, a malfunctioning battery is a serious fire hazard. Inexpensive lithium-ion batteries also present a serious risk of malfunctioning. Regardless, it’s important to never leave any e-bike battery charging overnight or without supervision.

It may sound excessive, but considering the number of buildings destroyed just this month due to these batteries, it’s worth taking precautions. New York Daily News reported that in the U.S. alone, charging lithium-ion batteries caused 330 fires from 2015 to 2018.

E-bike battery sparks another huge NYC blaze, guts grocery store and injures 7

An e-bike sparked a massive hours-long blaze that gutted a Bronx grocery store and injured seven people — two seriously — on Sunday, officials said.

On: fires

An EMS worker and a civilian were seriously hurt when flames broke out around 10:40 a.m. at the Concourse Food Plaza at 2096 Grand Concourse in the West Bronx section, officials said. Five firefighters suffered minor injuries.

The quick-moving fire was blamed on a scooter’s lithium-ion battery and rose to five alarms, requiring over 50 units and more than 200 firefighters to douse it.

Mayor Adams went to the scene and used the incident to call attention to the batteries, which have sparked a slew of recent fires in the city, some of them fatal.

“We have witnessed this over and over again, and that is why we’re going to continue to amplify the message that a simple device like this, this charred scooter, is only a symbol of what is happening behind us and what has continued to take place since early this morning,” Adams said Sunday afternoon. “We’re still fighting the fire because of the type of device the fire started from.”

The fire was blamed on a scooter’s lithium-ion battery, requiring over 50 units and more than 200 firefighters to douse it.

Fire Commissioner Laura Kavanagh said the bike caused “extraordinary damage.

“This entire building behind me is completely destroyed,” Kavanagh said. “The roof is caved in. There’s nothing left. And it is all because of this single bike.”

Firefighters could be seen carrying the burnt bike away from the scene.

Fires caused by e-bike batteries killed six people in the city in 2022, officials said. Those blazes were among 219 started by the batteries last year and left another 147 people injured.

Giant Electric Bikes Review

Giant is the world’s largest manufacturer of traditional bicycles and is expected to become the most dominant player in the e-bike market in the recent future as well, as Giant electric bikes are becoming more and more popular.

Apart from designing and producing its own bikes, Giant also manufactures bicycles for other major cycling brands, such as Trek, Scott, and Colnago. Therefore, it’s unlikely that you’ve never ridden a bike made by Giant.

If you’re considering adding one of its bikes to your collection, you should read our detailed Giant E-Bike review below. We’ll tell you all about the brand and the technologies it uses, as well as show you its electric bike lineup.

Are Giant bikes worth the money? Let’s find out!

About Giant Bicycles—Are They Really THAT Good?

Giant is a well-known brand that has possibly contributed the most to the world of cycling.

Giant is a member of the Giant Group, which was established in 1972, in Taiwan. It is the world’s largest manufacturer of high-quality bicycles and cycling gear and one of the most influential brands in the industry.

Giant Cadex 980C first mass-produced carbon fiber road bicycle.

As an independent brand, Giant was born in 1981 when the first Giant-labeled bicycles hit the stores, first in Taiwan, and then in North America, Europe, and other parts of the world. After that, it soon rose to stardom and became the biggest player in the game.

The thing that sets Giant apart from other brands is that it has always been the pioneer of change. Giant made its frames from lightweight aluminum when the industry’s standard was still steel. It was also the first to make carbon fiber bikes widely available to the world, revolutionizing the cycling experience.

Giant also transformed the look and feel of modern road bikes with its Compact Road technology, as well as improved off-road performance bikes with Maestro Suspension.

Today, Giant continues developing groundbreaking cycling technologies and manufacturing modern bikes, including e-bikes for recreational and practical use.

Giant’s Patented E-Bike Technologies

Giant has been around for almost 50 years. During that time, it has patented numerous technologies that have completely changed how we ride bikes and how we think about them.

Let’s take a look at some of the most important e-bike technologies that this company has developed so far. You can find most of these solutions on Giant’s electric bicycles. But it all depends on how much money you spend.

SyncDrive Pro

SyncDrive Pro is a technology that provides pedaling assistance that’s in tune with human input. Therefore, Giant’s bicycles are able to produce smooth pedaling power and a natural feel that ensures good performance and an enjoyable ride.

Smart Assist

Smart Assist technology uses complex mathematical calculations to determine exactly how much power a rider needs, based on their power input and the pedal-assist level.

EnergyPak

EnergyPak is Giant’s latest battery system that features an elegant design and full integration. The EnergyPak batteries are placed inside the bike’s downtube, so they’re not an eyesore. These batteries also charge up to 80% in 2.2 hours and offer a better range than regular batteries.

RideControl

RideControl is a handlebar-mounted command center that features special ergonomically designed controls. It lets you have full control over your e-bike and track important metrics such as distance, speed, battery level, and pedal-assistance level.

E-Bike App

Giant’s E-Bike App lets you connect your smartphone directly to your e-bike via Bluetooth. The app lets you tune the motor to get the best support ratio for your needs, use navigation, and track important fitness data.

Review of Giant Electric Bikes Lineups

When it comes to e-bikes, Giant’s selection is not huge at the moment, but it is pretty decent nonetheless. The company manufactures electric bicycles in several categories, including Road, Gravel, Mountain, and Lifestyle.

No matter if you are a regular rider who spins the pedals every day or if you haven’t sat on a bike saddle in decades, you’re likely to find a model that you like in Giant’s lineup.

Let’s take a quick look at each of the categories, learn about the individual model lineups, and find the best Giant electric bike for your personal needs.

LaFree E is not a road bike in the traditional sense of the word, but it is built to be enjoyed on the road. Giant LaFree is a city/commuter/comfort bike built to be appreciated on a daily basis by regular people, rather than hardcore cyclists.

It has a 60Nm SyncDrive Life motor and a 400Wh battery that together provide plenty of assistance and a decent range. The upright geometry will put you in a comfortable riding position and the rear rack allows you to carry groceries, a child seat, or anything else you need on hand.

Explore the neighborhood, get fit, commute, or ditch the car, LaFree E can do it all.

Giant Electric Gravel Bikes

Gravel bikes have become very popular because they give you more possibilities than any other type of bike. A gravel electric bike takes those possibilities to another level.

Ride farther than ever before, explore paved and unpaved roads, and keep pedaling even when you run out of road. Let’s see what Giant’s gravel e-bikes put on the table.

Roam E

Forget about the limits and start exploring more.

All the e-bikes you need in one affordable model.

Giant Explore E is the ultimate electric bicycle for the average rider. Unless you’re a performance-oriented road or MTB rider, you’ll probably like what Explore E is all about.

Giant Electric Mountain Bikes

A few years ago, few people could imagine that electric mountain bikes would wiggle their way onto trails. Today, the electric mountain bike market is the fastest growing one in the e-bike industry.

Giant electric mountain bikes let you enhance your singletrack adventures, climb steep hills, and conquer high peaks. climbs equals more descents, which comes without a recovery penalty if you do it on an e-bike.

Let’s see which models Giant offers at the moment and find out what they are good for.

Talon E

An e-bike for beginners to enjoy the perks of real trail riding.

Giant imagined the Talon E series to be a selection of affordable mountain bikes for trail beginners and those who simply want to enjoy some off-roading. Talon E is built around a sturdy aluminum frame and a 100mm fork, combined with massive 29″ wheels and tires for uncompromising on-trail rolling capabilities.

It uses a Giant SyncDrive Core mid-drive motor to push the rider, with 50 Nm of torque and 5 pedal-assist modes, plus automatic. The 400Wh battery is “hidden” inside the rather unwieldy down tube.

The traditional drivetrain has a Shimano Alivio 9-speed rear derailleur and a 36T chainring on the front. Tektro hydraulic disc brakes are easy to adjust.

We recommend it if you think it fits your needs.

Trance X E Pro

E-mountain trail bikes for big boys and even bigger trails.

Trance X E Pro is a serious electric mountain bike with full-suspension, 29″ tires, and aggressive slack geometry. If you want a Giant fat tire mountain bike and you have a big budget, there’s little you won’t like about these models.

The Giant’s mid-drive motor puts out massive 80Nm of torque for powerful climbing, with pedal-assist up to 20 mph. The battery has a 625Wh capacity, which translates to a lot of climbed hills.

The Fox suspension gives you 150mm of travel front and rear, whereas the 2.6″ Maxxis tires ensure both grip and confidence to shred trails.

Simply said, Trance X E Pro will let you hit trails as hard as before, if not even harder, as it is one of the best Giant electric bikes.

Stance E

A mid-range Giant full-suspension electric mountain bike for harsh terrain.

Giant Stance E is designed with trail-friendly geometry and rider-friendly components. This is a purebred full-suspension trail bike with 130mm of travel and a mid-drive motor that will send you flying up steep climbs.

The SyncDrive Sport motor is powered by Yamaha and develops 50Nm of torque, whereas the battery packs 625 Wh of additional juice.

Stance E bikes feature lightweight and efficient 1x drivetrains and uncompromising 29″ wheels. These ensure a good attack angle on fast descents. While descending, you’ll also appreciate the hydraulic disc brakes with giant rotors.

Are there any trails and descents waiting to be sent?

Fathom E

Versatile trail application with 27.5″ wheels and a dynamic motor.

e-bike, batteries, causing, fires

Giant Fathom E will let you take full control of trails thanks to its sport-optimized motor and versatile 27.5″ wheels with super-wide tires.

This bike excels on XC and singletrack terrain, where the SyncDrive Sport motor can help you reach a 20mph speed and the 500Wh battery can help you maintain it over a decent distance.

Fathom E bikes are reasonably priced, so they come with mid-range components that offer excellent value for the money. Examples of this include Shimano Deore components and Tektro hydraulic disc brakes.

This is a Giant electric bike for easier climbing and longer riding, deep into the sunset.

Reign E Pro

Reign the trails, both up and down, with the help of a mighty motor.

The Reign E electric mountain bike is the creme de la creme of Giant’s e-mountain collection. These are premium enduro bikes with high-end components and high-end prices. The top model costs 8,500. Ouch!

We’re talking about SyncDrive Pro mid-drive motors with up to 80Nm of torque and EnergyPak Smart 500Wh batteries integrated into the down tube.

Happy owners will also enjoy the high-end SRAM and Shimano drivetrains, brakes, and top-of-the-line 170mm suspension. These are 27.5″ electric mountain bikes, so handling is nimble and precise on demanding twisty trails.

You can’t go wrong with one of these Giants if you need their performance and their price fits your budget.

Momentum Lifestyle Electric Bikes

Momentum is a newly-established brand, founded by Giant. It makes so-called Lifestyle bicycles intended for casual, everyday use. If you’re an urban commuter looking to ride their car less, Momentum is a brand you should look into. These are also great bikes for recreational rides around the block, through the park, on bike paths, or for losing weight.

At the moment, Momentum manufactures three electric models called:

According to the info on the website, momentum was founded with a clear mission: “To help you move through life with happiness and ease.”

The three model lines available at the moment roughly cost between 2,100 and 2,800, which puts them in the entry-level to mid-range category. They include both step-over and step-thru frame variations, so they’re suitable for male and female riders.

Something they have in common is Giant’s SyncDrive mid-drive motors, hydraulic disc brakes, and a relaxed upright riding geometry. This makes them ideal for older riders, as well as those riders who don’t cycle too much but want to feel good when they do.

Momentum e-bikes are neither very lightweight, nor too fast (these are Class 1 e-bikes), but they look pretty and get the job done with ease. If you want a no-fuss e-solution, look into this Giant’s sister company.

Value for the Money—Are Giant Electric Bikes Too Expensive These Days?

Giant is one of the biggest, if not the biggest bicycle manufacturers in the world. That’s true for electric bicycles as well. Big-name brands are usually more expensive than small ones because they sell you both the bike and the branding. But is that true for Giant as well?

Actually, compared to some other big cycling brands like Trek, Specialized, or Canyon, Giant is a lot less expensive overall. That’s possible because Giant does the entire production and development process in one place, which allows them to cut costs, reduce overhead, and lower production times.

Therefore, even though you can definitely find cheaper e-bikes out there, Giant electric bicycles are not overly expensive. They offer pretty good value for money. Plus, buying from a big brand means that you will 100% get a replacement or a refund if your bike has a manufacturing defect. That’s not usually the case when purchasing cheap bikes off Amazon, even though you save at first.

What’s unique for Giant is that its e-bikes are fitted with proprietary technologies, such as SyncDrive motors and EnergyPak batteries. These are fitted on high-quality frames that are also built in-house by Giant. Therefore, all parts are compatible and work well as a package.

Ultimately, if you want an e-bike from a reputable and recognizable brand that offers good bang for the buck, you should probably get a Giant e-bike if there is one that fits your needs.
