Introduction & Quick Take

If you're shopping for an electric adult trike in Canada, the comparison between the ENVO Flex Trike and the Rad Power Bikes RadTrike is no longer just about features. It's also about long-term support, safety, and whether the company behind the product is still in a position to back it up.

The short version: the ENVO Flex Trike is the more capable, better-equipped, and more future-proof option for most Canadian riders. It offers a stronger drive system, a torque sensor, hydraulic brakes on all wheels, suspension, bigger tires, a foldable aluminum frame, and much better battery capacity. The RadTrike was originally appealing as a simpler budget-friendly option, but it is now discontinued, and Rad Power Bikes filed for Chapter 11 bankruptcy on December 15, 2025. With the Vancouver store closed as of January 9, 2026, warranty and parts support are now uncertain in Canada.

Who is each trike for? The ENVO Flex Trike is the better fit for riders who want comfort, range, cargo utility, stronger hill performance, and reliable support from a Canadian brand. The RadTrike made sense for casual, flatter-terrain riders looking for a basic entry-level trike, but in today's market, it's much harder to recommend as a buy in Canada.

Overview of Both Brands

The ENVO Flex Trike is built by ENVO Drive Systems, headquartered in Burnaby, BC. ENVO is one of Canada's most established e-bike manufacturers, with a national dealer network, a dedicated spare parts store, and years of engineering development specific to Canadian road, climate, and regulatory conditions. The Flex Trike is their flagship three-wheeled model — a purpose-built fat-tire adult trike with a foldable 6061 aluminum frame, torque sensor, rear differential, hydraulic brakes, 8-speed gearing, and an expandable dual-battery system capable of 220 km range.

The RadTrike was built by Rad Power Bikes, a Seattle-based company that grew into one of North America's largest e-bike brands before financial difficulties led to its Chapter 11 bankruptcy filing on December 15, 2025. The RadTrike is now discontinued. The company's only Canadian retail location — Vancouver, BC — closed permanently in January 2026, and the brand was sold at auction on January 22, 2026 for $13.2 million, a 99.2% decline from its $1.65 billion peak valuation. Warranty claims for bikes purchased before December 15, 2025 are no longer honoured.

Even before the bankruptcy, the specifications told a clear story. The ENVO Flex Trike is built to a substantially higher technical standard: torque sensor versus cadence sensor, rear differential versus no differential, 720 Wh versus 480 Wh, fat tires versus narrow 18" tires, hydraulic brakes all-round versus a coaster brake at the rear, and 8-speed gearing versus single-speed. The bankruptcy simply removes any remaining ambiguity about which trike is the wiser investment for a Canadian buyer in 2026.

Full Spec Comparison Table

Performance & Power

ENVO Flex Trike — rear-mounted hub motor with mechanical differential, 80 Nm torque, and precision torque sensor for natural power delivery on every pedal stroke

The performance gap between these two trikes is wide. The ENVO Flex Trike is rated to 32 km/h — fast enough for bike lanes, secondary roads, and mixed urban-suburban riding. The RadTrike's top speed is not published by Rad Power Bikes; anecdotal reports place it around 22–24 km/h, which in many Canadian cities cannot match bike lane traffic.

The sensor type difference is equally significant. The ENVO Flex Trike uses a torque sensor, meaning motor output responds directly and proportionally to how hard you pedal. Push harder on a hill — more power. Ease off on a flat — assist fades naturally. The RadTrike uses a cadence sensor, which simply detects when you are pedalling and applies a fixed level of assist regardless of load or effort. On hills, flats, and starts from rest, the feel is blunter and energy is deployed less efficiently.

Motor placement also matters. The ENVO Flex Trike places its motor at the rear axle with a mechanical differential, allowing the inner and outer rear wheels to rotate at different speeds during turns. The RadTrike uses a front hub motor with no differential. This layout can create handling imbalance under motor assist, particularly in wet conditions or on uneven surfaces. The ENVO's rear-drive with differential architecture is the correct engineering choice for a three-wheeled vehicle.

Battery & Range

The ENVO Flex Trike carries a 720 Wh battery (48V / 15Ah) built with LG or Panasonic lithium-ion cells and a protective BMS rated for cold-weather operation — relevant for Canadian riding conditions from October through April. ENVO rates the Flex at 50–100 km per charge depending on assist level, rider weight, and terrain.

The RadTrike packs a 480 Wh battery (48V / 10Ah) — 33% smaller than the Flex's standard pack — with a published range of 32–56 km (20–35 miles). This is a narrow window that reflects both the smaller battery and the cadence sensor's less efficient power delivery.

The ENVO Flex Trike's decisive battery advantage is its dual-battery system. Adding a second 48V / 17.5Ah pack brings total capacity to 1,560 Wh — more than three times the RadTrike's battery — with a claimed range of up to 220 km per charge. The RadTrike has no dual-battery option at any price. For riders who tour, commute long distances, or simply want to go weeks between charges, this expandable architecture has no equivalent in the RadTrike lineup.

Safety & Certifications

The ENVO Flex Trike carries full UL 2849 system certification — the motor, battery, charger, controller, and wiring validated as an integrated system by Underwriters Laboratories

Both trikes address the UL 2849 electrical safety standard — but the nature of that compliance differs. The ENVO Flex Trike carries full UL 2849 system certification, meaning Underwriters Laboratories directly validated the motor, battery, charger, controller, and wiring as a complete integrated system. This is the UL Listed mark that Canadian building managers, condo boards, and insurers are increasingly recognising as the benchmark for indoor charging approval.

The RadTrike is ACT lab tested to comply with UL 2849 — a legitimate safety compliance pathway where a third-party lab tests the product against the UL 2849 standard. This means the RadTrike has undergone meaningful safety testing and meets the standard's requirements. The distinction from full UL certification is the testing authority: ACT-tested compliance vs. the UL Listed mark itself. For most riders both provide a solid safety baseline; for managed buildings or insurers specifying UL Listed products specifically, the difference matters.

A separate concern Canadian buyers should understand: in November 2025, the U.S. Consumer Product Safety Commission issued an urgent warning regarding Rad Power Bikes battery packs, citing 31 fire incidents and over $734,500 in property damage. The affected models were the RadRunner 2, RadRover 5, RadWagon 4, RadCity, and RadExpand 5 — not the RadTrike. However, Rad Power Bikes refused to agree to a recall, and the company filed for bankruptcy in December 2025.

Build Quality & Components

The component-level gap between these two trikes is substantial. The ENVO Flex Trike is built to a higher specification in nearly every category:

Handling & Stability

Electric trikes require specific engineering to handle correctly — particularly a rear differential, which allows the inner rear wheel to rotate slower than the outer wheel during turns. Without a differential, both rear wheels are locked to the same speed, causing the inner tire to scrub and drag through corners, reducing stability and putting uneven stress on the drivetrain.

The ENVO Flex Trike uses a rear differential, meaning both rear wheels rotate at appropriate speeds through every turn. Cornering is smooth, predictable, and controlled — important for senior riders and anyone carrying loaded cargo. The RadTrike uses a front hub motor with the left rear wheel spinning freely on the axle. This asymmetric design can cause handling imbalance under hard motor assist, particularly on gravel, wet pavement, or tight corners.

On tire width, the ENVO Flex Trike's 20" × 3" fat knobby tires provide a wide contact patch for stability across gravel, hard-packed trail, light snow, and wet road surfaces. The RadTrike's 18" × 2.25" tires are standard-width — not fat tires. This narrower profile reduces traction surface and ride cushioning on rough or loose terrain.

Cargo & Payload

ENVO Flex Trike with rear cargo basket rated at 150 lbs — the only fat-tire electric trike that folds for storage, transport, and apartment living

The ENVO Flex Trike is the only folding fat-tire electric trike on the market. Its 6061 aluminum frame folds down for apartment storage, vehicle transport, and ferry or transit use — a capability no other fat-tire trike in this category offers. The RadTrike has fold-down handlebars but does not fully fold and requires dedicated storage space for transport.

On cargo, the ENVO Flex Trike ships with a rear cargo basket rated at 150 lbs plus a front rack, for a combined payload capacity of 400 lbs (180 kg). The RadTrike's payload capacity is listed at 415 lbs — a marginal advantage. For riders who carry groceries, equipment, or use the trike for errands and light delivery, the Flex's 150 lb rear basket is a meaningful practical advantage over the RadTrike's smaller rack capacity.

Canadian Support & Parts Availability

ENVO Drive Systems is headquartered in Burnaby, BC — parts are stocked in Canada, dealers span every major Canadian city, and support is genuinely local

This is the category where the comparison becomes most one-sided — and where the stakes for Canadian buyers are highest.

ENVO Flex Trike — Parts & Support

ENVO operates a dedicated spare parts store covering the full Flex component catalogue — batteries, motors, controllers, displays, brake components, and drivetrain parts — stocked and shipped from Canadian inventory. No customs, no currency conversion, no cross-border delays. The Flex uses a Shimano drivetrain and Tektro hydraulic brakes, meaning any local Canadian bike shop can service the non-electric components with off-the-shelf parts. ENVO's national dealer network covers every major Canadian city, and the company provides bilingual English and French technical documentation.

RadTrike — Parts & Support

Rad Power Bikes filed for Chapter 11 bankruptcy protection on December 15, 2025, with $32 million in assets and $73 million in liabilities. The company's only Canadian retail location — Vancouver, BC — closed permanently in January 2026. Rad stated it cannot support warranty claims for bikes purchased before December 15, 2025. The business was sold at auction on January 22, 2026 to Life Electric Vehicles Holdings Inc. for $13.2 million — a 99.2% decline from its peak $1.65 billion valuation. For Canadian RadTrike owners, this means no warranty, no local Canadian dealer, uncertain parts supply, and any service requiring cross-border shipping with associated duties and currency costs.

Value & Pricing

The RadTrike was priced at approximately $2,499 USD (~$3,400 CAD) before Rad's bankruptcy — making it more expensive in Canadian dollars than the ENVO Flex Trike's $2,999 CAD sale price at EbikeBC (MSRP $3,429 CAD). For a higher Canadian-dollar price, the RadTrike delivers a smaller battery, narrower tires, cadence sensor, single-speed drivetrain, coaster rear brake, rigid fork, steel frame, no folding, and no dual-battery option — along with a bankrupt brand and uncertain parts supply.

Final Verdict

In most trike comparisons, each bike earns meaningful wins in specific categories. That is not the case here. The ENVO Flex Trike outperforms the RadTrike in motor sensor technology, top speed, battery capacity, range, tires, brakes, gears, suspension, frame material, safety certification, portability, and after-purchase support. The RadTrike's genuine advantages — a backrest saddle, a reverse throttle function, and a slightly higher payload limit — are comfort features that do not come close to offsetting the technical and support gap.

The ENVO Flex Trike is the clear choice for Canadian e-trike buyers in 2026. It is built in Canada, sold in Canada, and supported in Canada — with an active dealer network, stocked parts, and a product specification that surpasses the RadTrike in every meaningful performance category. The fact that it is also priced lower in CAD than the RadTrike's USD equivalent makes the decision straightforward. The Flex is available through EbikeBC with local test ride availability and knowledgeable support.

The RadTrike is no longer a recommended purchase for Canadian buyers. With Rad Power Bikes in bankruptcy, Canadian warranties voided, the Vancouver store closed, and parts support uncertain under new ownership, the ownership experience for a RadTrike carries genuine long-term risk.
